Beautiful visuals and well worth the effort as they make SO much difference in getting these ideas across. The attention to detail in the colors, the amplitudes, the transition to photons, etc. is all brilliantly effective.

Sir what if we consider the electric field of the electromagnetic wave is responsible for the ejection of electron instead of the imagining as photon like we did in reflection of light So higher the frequency the electric field wave the more the energy causes the of the light And thanks for this amazing explanation
explanation why light is weird: we are looking into the boundary of universes resolution, you cannot draw a perfect circle on your monitor, if you zoom in enough there are only strait lines, light is the same, cannot draw a perfect wave without infinitely small resolution, therefor we get discrete small points
Very comprehensively defined the concept of photo electric effect. Thanks for that.
i like the intuition of Mahesh,much respect sir!
Thank you very much for this video . I had sound understanding with this video

Simple as possible
Clear and concise
Waves of light
Packets of light
Wavelengths of light hitting metal
Packets of light hitting metal
Releasing electrons in the photoelectric effect
The higher the frequency
The more electrons ejected depending upon the metal reflected
The teacher explains with potassium as the base metal
Using the rainbow red orange yellow green blue indigo violet
To show how the various energies of light colors
Affect a substance such as a metal
With the ejection of electrons depending upon the required energy from the wavelengths or pockets of light energy
Thank you Khan academy
Carl Sagan would be proud
Physicist rule
Origins of order in biology
Patterns of nature
Repeating in the living room

6 vold symmetry
Spherical oil and water
Rainbow Brite
The arm patterns are used over again
The organ patterns are used over again
The human body is not an ad hoc contraption
Built piece by piece by piece
Bit by bit
But there is self-organization at a higher level of order
Repeating the organs
The limbs and fingers
Patterns of a deeper nature
Thank you Khan academy
very good explanation
Thanks a lot Mahesh Sir
I have one question. Why don't multiple photons of less than 2.3ev 'team up' to combine their energy and cause the emission of an electron?
Sir what if we consider the electric field of the electromagnetic wave is responsible for the ejection of electron instead of the imagining as photon like we did in reflection of light
So higher the frequency the electric field wave the more the energy causes the of the light
And thanks for this amazing explanation
Wow will that help with Gamma effect on meatal?
Can the wave nature associated with a photon be referred to as matter waves?
Does anyone know what app can i use to write documents like this style?
Thanks

Pls tell me the name of this teacher, I only want to watch the video when he's explaining.
