Question

If the period of a wave decreases, its frequency must ____________.

Answer 1

For this one if the waves decrease then it must mean that it’s frequency has Decreased as well

Answer 2

Answer:

Increase

Explanation:

The time period depicts the amount of time taken for completing one cycle of vibration. While frequency is the measurement of a number of cycles in a unit time.  

Therefore, both the period of wave and frequency are inversely proportional to each other. The higher will be the time period, the lower will be the frequency and vice versa.
