Question
When we decrease the wavelength of a wave, the frequency
- Increases
- Decreases
- Remains constant
- Becomes zero
Hint:
Frequency is inversely proportional to wavelength.
The correct answer is: Increases
- Wave speed= frequency × wavelength
- Frequency is inversely proportional to wavelength.
- Therefore, on decreasing the wavelength frequency increases.
- So, the correct option is a.
