Question

Find the frequency of a wave with a period of 0.5 seconds

Answer 1

Frequency = 1/time period
=1/0.5
=2Hz

Answer 2

Answer:

2 Hz

Explanation:

Frequency can be defined as the number of waves in one second. It is measured in Hz. 1 Hz = 1 /s.

Time period is time taken by a wave to complete 1 oscillation. It is measured in s.

Thus, frequency and period are related as:

f = 1/ T

T = 0.5 s

Thus, f = 1/0.5 Hz = 2 Hz
