If a wave gets refracted into a denser medium, then which of the following is true?

Options

  1. AWavelength, speed and frequency decreases.
  2. BWavelength increases, speed decreases and frequency remains constant.
  3. CWavelength and speed decreases but frequency remains constant.
  4. DWavelength, speed and frequency increases.

Correct answer

C. Wavelength and speed decreases but frequency remains constant.

Step-by-step solution

In refraction from one medium to another, the speed and wavelength gets changed. The frequency remains unchanged.
