Answer 1

Answer:

ᕼᗴY ᗰᗩTᗴ✌︎

.

Explanation:

The frequency (f) of a wave is the number of full waveforms generated per second. This is the same as the number of repetitions per second or the number of oscillations per second.  

Time Period (T) is the number of seconds per waveform or the number of seconds per oscillation.

Tℎᴜs,

120/25 = 4.8.

But if the secs are 2.5,

120/2.5 = 48.
