Ocean waves are hitting a beach at a rate of 3.2 Hz. What is the period of the waves? (2 decimal places)

The period of the wave is 0.31 s.

The question above can be solved using the relationship between period and frequency (T = 1/F).

Frequency: This can be defined as the number of complete oscillations performed by a wave in one second.

Period: This is the time required by a wave to complete one oscillation.

The relationship between period and frequency

Formula:

T = 1/F Equation 1

Where:

From the question,

Given:

Substitute this value into equation 1

Hence, the period of the wave is 0.31 s.

0.31s

Explanation:

Given parameters:

Frequency of the ocean waves  = 3.2Hz

Unknown:

Period of the waves  = ?

Solution:

The period of a wave is the inverse of the frequency of a wave;

       Period  =

Now insert the parameters and solve;

       Period  =   = 0.31s

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

find the surface area of the sphere to the nearest square unit. use a calculator.
