light wave has a wavelength 4100 A
in glass. If the R.I of the glass is 1.5
find the wavelength of light in the air?​

Answer 1

Answer:

R.I of the glass = 1.5

Wavelength of light in glass = 4100 A

R.I = Wavelength of light in air /glass

1.5 = wavelength of light in air / 4100

Wavelength = 1.5 × 4100

6150 A ANS
