What is the frequency of this wave?

10 waves/sec
0.1 wave/sec
cannot be determined

Answer 1

Answer 2

The period tells you how many seconds are required to complete one cycle, while the frequency tells you how many cycles occur in one second. So, frequency is just the reciprocal of period.

You just found the period, so the reciprocal of that is the frequency (f=1/T).

Answer 3

10 waves/sec?

Answer 4

i didn't really get it...

Answer 5

Well, you just tole me the period was 10 seconds. That means it takes 10 seconds to complete 1 cycle of the wave. If that's the case, how many waves occur in only 1 second?

Answer 6

0.1

Answer 7

right?

Answer 8

Yup

Answer 9

thanks and the last question

Answer 10

What is the approximate amplitude of this wave?

15 centimeters
30 centimeters
15 seconds

Answer 11

15 seconds right?

Answer 12

15 centimeters but yes lol

Answer 13

Amplitude is a measure of distance, not time, so units need to be cm, not s. Just look at the units of the y-axis!

Answer 14

Thank you:))))
