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 = 6×10−72.4×108
= 4 × 1014 Hz
