Question

light of wavelength 500 in air enters a glass plate of refractive index 1.5 find speed,frequency and wavelength of light in class​

Answer 1

Answer:

Give that wave length 500 nm and then glass plate had 1.5 wave length of the light in the vacuum. then 2x108 ms-1 and here the light in the glass go = λvng = 550 nm1. 5 = 300 nm.
