Question

(a) Compare the speeds of light of wavelength 4000Å
(i.e. violet light) and 8000 Å (i.e. red light) in

vacuum.​

Answer 1

Hey bro,

Since, Velocity(V) = Frequency × wavelength.

But, since wavelength of all lights travel in vaccum with the same speed.

Therefore, the ratio of their velocities will be 1:1.

Hope, it finds uh better.

Answer 2

Answer:

1:1

Explanation:

since both lights travel in vacuum hence speed is =3*10⁸

on comparing ,

1:1
