Answer:
B. 2 Hz
Explanation:
Given parameters:
Period of the wave = 0.5Hz
Unknown:
Frequency of the wave = ?
Solution:
Frequency is the number of waves that passes through a point.
Period is the time taken for a number of waves to pass through a point.
Period is the inverse of frequency
Frequency = [tex]\frac{1}{t}[/tex]
t is the period
Frequency = [tex]\frac{1}{0.5}[/tex] = 2Hz
