Question:
The frequency of a light ray is \( 6 \times 10^{14} \) Hz. Its frequency when it propagates in a medium of refractive index 1.5, will be:
The frequency of a light ray is \( 6 \times 10^{14} \) Hz. Its frequency when it propagates in a medium of refractive index 1.5, will be:
Show Hint
Remember that the frequency of light does not change when it passes through a different medium, only the wavelength changes.

- \( 1.67 \times 10^{14} \) Hz
- \( 9.10 \times 10^{14} \) Hz
- \( 6 \times 10^{14} \) Hz
- \( 4 \times 10^{14} \) Hz
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The frequency of light remains constant when it passes from one medium to another, only the wavelength changes. Therefore, the frequency in the new medium will remain \( 6 \times 10^{14} \) Hz.
Thus, the correct answer is option (3).
