Question
Which of the following properties of a light wave remains constant in every medium of travel?
- Wavelength
- Frequency
- Intensity
- Energy
Hint:
Frequency
The correct answer is: Frequency
Frequency of the light wave remains constant in any medium so when light wave goes rarer to denser medium, it's speed decreases hence the wavelength of the wave also decreases.
