The wavelength of a beam of light in air...

The wavelength of a beam of light in air is `5000 Å`. Find the number of waves of the beam in 10 cm of glass of refractive index `1.5` k

Text Solution

Verified by Experts

The correct Answer is:
`3 xx 10^(5)`
The number of waves in 10 cm of glass = wave number in glass `xx` path length
