Light of frequency 6.0 x 1014 Hz travelling in air is transmitted through glass or refractive index 1.5. Calculate the frequency of the light in the glass
-
4.0 x 1014Hz
- 6.0 x 1014Hz
- 7.5 x 1014Hz
- 9.0 x 1014Hz
The correct answer is: A
Explanation
1.5 = \(\frac{6 \times 10^{14}}{F}\)F = 4 x 1014Hz
