Question

When light is refracted, which of the following does not change?

• A. Wavelength
• B. Frequency
• C. Velocity
• D. Amplitude

Hint:

In refraction, the frequency of light remains constant, but its wavelength and velocity change due to the properties of the new medium.

Answer 1

The Correct Option is B

Step 1: Understand the concept of refraction.
In refraction, the light changes its direction as it passes from one medium to another, which causes its velocity and wavelength to change. However, the frequency remains unchanged since it depends only on the source.
Step 2: Conclusion.
The frequency of light does not change during refraction. Final Answer: \[ \boxed{\text{Frequency}} \]
