15 waves in=3sec.

1wave=1/5sec.

Time period=1/5 seconds

As we know that frequency=1/time period

Frequency=5 Hz.

Answer:

5 hz

0.2 s

Explanation:

frequency basically means the number of waves traveled per second

since 15 waves occurred in 3 seconds ,

we'll simply divide 15 by 3 to calculate the number of waves per second

15/3 = 5

hence, 5 hz is the frequency

as of time period, it means amount of time required for one wave to travel.

f = 1/T

5 = 1/T

5T = 1

T = 1/5 = 0.2 sec

that's it!
