Question

Wavelength range of white light in air is 4000 Å to
7000 Å. Find the wavelength range of white light in water
u = 4/3).
​

Answer 1

Answer:

let wavelength in water is W

wavelength in air is A

u =4/3

by formula

W = A/u

W = 4000/(4/3)

W = 3000Å (minimum)

W = 7000/(4/3)

W= 5250Å (maximum)

=> wavelength range of white light in water is

(3000Å - 5250Å)
