Question
When we increase the wavelength of a wave, the frequency
- Increases
- Decreases
- Remains constant
- Becomes zero
Hint:
Frequency and wavelength are inversely proportional.
The correct answer is: Decreases
- Frequency= Wave velocity/wavelength
- Frequency and wavelength are inversely proportional.
- Therefore, increasing the wavelength decreases it's frequency.
- So, the correct option is b.
