Question

A ray of light of wavelength 5400 A suffers refraction fromair to glass. Taking a Mew g=3/2, find the wavelength of light in glass......
plse do it fasssssttttt....it is argent...​

Answer 1

Answer:

actualy we don't need the wavelength

refractive index = speed is out the in air/ speed of light in glass

3/2= light in air / light in glass

speed of light in glass = 2/3 * speed of light in air

speed of light in glass = (2 * 3*10^8)/3

speed of light in glass = 2 * 10^8

because 3 cancels out
