Question

for the same angle of incidence in medium A B and C the angle of reflection at 20 degree 30 degree and 40 degree respectively in which medium will the velocity of light be maximum give reason

Answer 1

gosoysus

$4655 + + - \times 2$

Answer 2

here is your answer :-

the velocity of light will be maximum at 20 degree...
this is because we know that,
action = reaction ( newton 3rd law )
so , as we know that light will strike the object with its max. at 20 degree
therefore through newton's 3rd law if light strikes the obstacle with 10 m/s then reaction will also be 10m/s...
THIS WILL BE THE ANSWER IF THERE ARE DIFF MEDIUM

IF THE MEDIUM IS SAME THEN THE ANSWER WILL BE - EQUAL

as speed of light is 3×10^8
which will be initial velocity

I hope this will help. ..
