"If a floating log is seen to bob up and down 15 times in 1.0 min as waves pass by you, what is the frequency of the wave?"

Respuesta :

AL2006

(15 times) / (60 seconds) =

(1/4 time) / (1 second)

That's 0.25 Hz.

The frequency of the wave which bob up and down 15 times in 1.0 min is 0.25 Hz

What is frequency?

This is the number of complete oscillations made in one second. It can be expressed mathematically as:

Frequency (f) = number of oscillation (n) / time (t)

f = n / t

How to determine the frequency

  • Number of oscillation (n) = 15
  • Time (t) = 1 min = 1 × 60 = 60 s
  • Frequency (f) =?

f = n / t

f = 15 / 60

f = 0.25 Hz
