deadass saved my life on this one 3am grind with these vids
three years later, im doing the exact same thing at the same time in the morning lmao
Fr
frr
frr
Pays 25k a year for tuition...ends up being taught by a youtube tutor (both chemistry and calculus)...what a great system lol
Thanks for making great videos so I can learn this stuff!
wow that is one expensive school.
oh boy my parents pay 40k a year for tuition. i always end up at youtube for tutors that i can easily understand
@@nanamikents1760 go to france
College is way too expensive, often not worth the money unless your major can make 6 figs
dude im learning this in AP chem lol
This channel is going to be the only reason I pass chemistry
same over here
@@1829Emily hi
at least you're gonna pass..
unlike me
@@red-sv2qf You are going to pass I know you will. I used to get F's but after discovering this channel I get C's and B's, if I'm lucky and A.
im using this for physics.
i'm dying to know who this person is. such an angel
i really appreciate your voice, tone, pace and the way you explain things. it's relaxing yet still engaging to listen to.
I learned so much in so little time!! Thank you Professor!
This channel is such a life saver
You're life saver, it seems very easy to me now❤️
Thanks alot👍
These videos are the only ones I am completely okay watching ads for. You deserve it
This helped me so much, thank you.
Professor Organic Chemistry Tutor, thank you for another great video/lecture on How To Calculate The Energy of a Photon Given the Frequency and Wavelength in General/AP Chemistry. This material is easy to follow provided that the correct formula is used to produce the solution. This is an error free video/lecture on RUclips TV with the Organic Chemistry Tutor.
You saved me from miserably failing my test over electron configuration
Fannı. I’m about to fail mine 😂
2 years ago original comment, 1year ago reply above, and now I take mine today
I take mine the 23rd
I’m literally abt to take my test n I’m gonna fail
@@tapesnsnippets i take mine in 2 weeks over electron configuration lmaooo
Best video ever ! Literally saving me right now !
Thank you so much! So simple and straight forward😊👍
Thank you so much! I was so confused but this was amazing and now I understand!!!
I love this guy, couldn't get through chem 122 at UTK without him
This's the only channel that makes me love Chemistry.
Thank you so much...... your explanation helped me a lot
Thanks so much! This video helped me a lot with Inorganic Chem.🙏
Thank you for absolutely everything!
Life saver you are! Fine master you will become
How re you this good in explaining stuff
i get the base number right, but not the exponents :'(
press ENG after you get the base number
2 years hhhhhhhhh\
@@muhali5136 how do i write 500 nanometer to 500 x 10 something? i wanna know
Where did you get the exponent -19????
Mass of electron is 1.6*10^-19 it is fixed
Thank you 😩♥️ your my lifesaver
Thanks,now I may have a chance at my Physics exam
Dude, ur video helps me a lot!!!! Thank you soooooooooo much!! )
is anyone else not getting the same answers as he is? I'm typing in everything correctly and my numbers are very different than his. I've also tried two different calculators
If you’re talking about 3:47, I got it wrong as well. Turns out, you have to divide by 5.00 x 10^-9, not 500. Thats what worked for me.
@@alyssarose2818 You're a life saver! I was wondering where -19 came from when I recalculated again and still got 3.98*10^-37
Ah nope my exponents are still not matching up :(
@@spcchckn ~ make sure to use parentheses if you’re using a calculator!
@@spcchcknparenthesis for each thing
i have learned so much from you .Thanks
You made my life easy...🌹
This channel is really wonderful
Thanks so much 🔥🔥🔥🔥
I'm a software engineer with zero chemistry i was working on a light simulation using rendering this is helpful thanks
Class video as always, cheers
THANK YOU SO MUCH!!!!!!!!!!!!!
Yow bro.. You have another save life bro.. Wonderful ❤
Your videos save lives
Hello Friend. Please upload videos on UV/VIS, IR, 1H-NMR, 13C NMR and Mass Spectrometry. These important topics are underrated on RUclips.
Love this channel...saved me way to many times istg
There is an immediate problem with this equation, that I have never seen addressed in a video: That implies that the energy of a photon is associated with its color at a fundamental level. That implies that the Doppler effect is magic, or that frequency and therefore time are relative to movement. This is a nice connection.
For problem #2 Make sure you put brackets around them like this: (6.626x10^-34)x(3x10^8)/(500x10^-9)
Thanks, Obama
Oh my God. I can't explain how i am so thankful of you sharing this. I am assigned as a student teacher tommorow for Science and afraid i might teach my classmates the wrong way! Thats why i am also confused as to why the answer in my calculator is different from the video, so its all about adding brackets.
The thing is, _when will you add brackets?_
I love that RUclips teachers are always better than my teachers at my school
Thanks ..I really like it 👍👍
I have a retake test tomorrow and this actually saved me
Thanks 😀 men and
God bless you.
top video. best way to learn is by plenty of examples in my opinion
Thanks for your this information ☺️☺️☺️
this guy is the best!
THANKS YOY SO MUCH YOU SAVED MY LIFE
i love your channel .it. has. saved. me.
New Photon equation
P=ETC2 vs E=mc2
Please share
Thank you so much😭👏❤️
Wow your better than my teacher
thanks for saving my chem grades
you are the best!
Thanks for such a video
Love from 🇮🇳 india
1:37 how did u get -22 from -34 and 9
I'm getting 3.98x10^-17. I have everything bracketed, what am i doing wrong?
ThePixelFighter calculator might be set to radiant not degrees , change that in the mode setting
Wow thank you so much!!!!!!!!
Thank you ❤️
you the man homedog
Thank you
Calculate the energy for a single photon of two lights given below (h = 6.626 x 10-34 J s). Do the energy values make sense? How? (𝑬 = 𝒉𝝂 = 𝒉𝒄), (𝑐 = 3.00×108 𝑚/𝑠),
(h = 6.626 x 10-34 J s) (109 nm= 1m)
thank you for thisss
For Problem #2 and #3, if anyone got the exponent - 31 using a scientific calculator, and it didn't align with the video which is - 19, simply add brackets to those 3 given, and add a multiplication sign between the two converging parentheses.
For example
(6.626 x 10^-34) x (3 x 10^8) ÷ (240 x 10^-9)
Which would equate to
8.28 x 10^-19
As per shown in the video.
If you get
8.28 x 10^-31
Instead, its because you forgot the parentheses, and that multiplication sign in between i guess.
This was very helpful, thanks so much
Got a chemistry exam in about 3 hours. Life saver! Love from Nigeria! ❤️
How was the exam😏?
The best bro
Thankyou bro ❤
Mid-year Physics exam tomorrow and i was completely unaware of this entire topic because I was admitted to the grippy sock hotel when the teacher did this
Always the night before the papers>>>>>>🔥
Thanks
DUUUUUUUUUUUUUUUUUUUUUUDE I GET IT NOW !! IN THE UNIVERST I'LL BE LIKE "WTF IS THIS" XD
I have a test in like 20 mins tysm
Thank you so much! I finally understand
How do you put this in the calculator, I always get the wrong exponent.
What calculator are you using?
Bruh you better than my actual chemistry teacher
Sir, I need help figuring out hour to start out the problem: How much energy would be required to melt 10,700 g of ice?
I don’t know how to even start it! Can you explain what I must do in order to solve this problem
My calculator ain't giving me the right exponents but answer. However u made me pass my first semester of chemistryif I never came to u I probably would have failed
What kind calculater use to calculate this
how to calculate inverse of Planck constant
I got the answer but why it's raised to the power of -19 instead of -37?
same im trying to understand this too. glad im not the only one
How do you get that correct exponent? When I enter into a calc it gives me 33 or whatever not -19
help I got 3.9756E-37 how do I convert it to 3.98E-19
I wonder if this guy ever gets tired of the comments saying how broken the school system is or how he saved them from chemistry. Well, THANKS ANYWAY
Thanks american I am from India
😂
How do you get the -19 part tho because when I do it I get 17
PUTANGINA!❤ IN LOVE NA YATA AKO SA CREATOR NG CHANNEL NA ITO. YOU ALWAYS SAVE MY ASS SA MGA MAJOR SUBJECTS KO *SIGHS*. PUTA, GUSTO NA ATA KITA PAKASALAN. ❤❤❤
charrr GAGOOO NAGULAT AKO AHHAHAHAHAH
owow thanks, savior
7:48 I typed in everything exactly like it was on screen and I got 1.325 E to the -33. I use the EE for all the 10 to the (insert power) on my TI 84 + calculator. It is set to degrees. Why am I not getting 1.325 E to the -18 as shown on screen?
you're probably not including the parenthesis for the first number as well
@@kairymizu9530 What does this mean 😭
@@kairymizu9530 I'm having the same problem
those the constant gose with physics solving for the , Einstein photoelectric effect
For the second problem, how do I put all that in a calculator? I keep getting syntax errors
im not getting the same exponents
I love you
Super
legend
how did he get the -22?
I just knew organic chemistry was going to help me out. My professor sucks fr
help. For number 2, I typed the equation and I used a energy calculator, but I got 2.4797 eV both times. Help
Where are you gettin the numbers from
