manish maurya If I=r=0, we can’t use the formula sin I/sin r, because no matter what pair of media it is, It will ALWAYS return 1 right?The formula breaks down here. So if we want to find the refractive index when I=r=0, we simply use the other definition: RI= (speed of light in 1st medium)/(speed of light in the second medium)

Me: "OMG Khan academy just dropped a bunch of videos!"
Good meme! OMG 9-Volt just dropped a bunch of subscribers! (I mean I gained a lot of subs!)
Can i use this definition sin I /sin r=constant when I=0 and r=0
Nah that’s an exception
@@meltdown6856 then how can i find refractive index when sin I=0 and sin r =0

Hope that helped :)

Wait! Why is physics on Khan Academy Medicine? It does not belong!
Even though I am in 11th grade (also 11 years old), I am too young to study this...
Why am I watching this?
