Chapter 9, Problem 13STP

(A)

To determine

The frequency of the wave for the given illustration.

Answer to Problem 13STP

The frequency of the wave shown in illustration is 2 Hz.

Explanation of Solution

Given:

The given wave is shown below.

  

Length of x-axis is 2 seconds.

Formula used:

The number of cycles of the particle in a second is called the frequency. The more the number of cycles in a second, the higher is the frequency of the particle.

Calculation:

There are four cycles of the wave in $2\text{s}$ . So, the number of cycles in one second is two. The frequency of the wave is $2\text{Hz}$ .

Conclusion:

Therefore, the frequency of the wave shown in illustration is 2 Hz.

(B)

To determine

The frequency of the wave for the given illustration.

Answer to Problem 13STP

The frequency of the wave shown in illustrationn is 1 Hz.

Explanation of Solution

Given:

The given wave is shown below.

  

Length of x-axis is 2 seconds.

Formula used:

The number of cycles of the particle in a second is called the frequency. The more the number of cycles in a second, the higher is the frequency of the particle.

Calculation:

There are two cycles of wave in $2\text{s}$ . So, the number of cycles in one second is one. The frequency of the wave is $1\text{Hz}$ .

Conclusion:

Thus, the frequency of the wave shown in illustration is 1 Hz.

(C)
