Question
Which of the following waves shows the highest frequency?
Hint:
Frequency is the number of waves that pass a fixed point in unit time.
The correct answer is:
- Frequency of a wave is the number of cycles in a given time.
- In the given picture highest frequency is for wave-1 and lowest is for wave-3.
- So, the correct option is a.
