Answer:
Frequency= 0.25m
Period= 4.0 secs
Explanation:
Clay is surfing on a wave with a speed of 5.0m/s
The wave crests are 20m apart
Therefore, the frequency of the wave can be calculated as follows
Frequency= wave speed/distance
= 5.0/20
= 0.25m
The period (T) can be calculated as follows
T= 1/frequency
T = 1/0.25
T= 4.0secs
Hence the frequency is 0.25m and the period is 4.0 secs
