Electromagnetic radiation of frequency n, wavelength λ, travelling with velocity v in air, enters a glass slab of refractive index µ. The frequency, wavelength and velocity of light in the glass slab will be respectively
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
In going from one medium to another, frequency remains same but wavelength and velocity decrease with the increase in refractive index i.e., wavelength becomes 
and velocity becomes,
