Question

If the time period of a wave increases, then its frequency will

• A. Increase
• B. Decrease
• C. Remain the same
• D. First increases then decreases

Answer 1

Answer: (B)

Decrease

$f=\frac{1}{T}$

$f\to frequency$

$T\to timeperiod$

Frequency is inversely proportional to the time period of the wave. So when time period increases then the frequency will decrease.
