Relative refractive index of two media is 0.80. In one of them, light has wavelength 6000Å and travels at 2.4 × 108 m/sec. This light is refracted into the second medium. Its frequency in the second medium is –

A

4 × 1014 Hz

B

6 × 1014 Hz

C

2 × 1014 Hz

D

3.2 × 1014 Hz

Answer

4 × 1014 Hz

Explanation

Solution

ν = 2.4×1086×107\frac { 2.4 \times 10 ^ { 8 } } { 6 \times 10 ^ { - 7 } }

= 4 × 1014 Hz
