**Possible Answers:**

**Correct answer:**

The relationship between frequency and period is .

Plug in our given value:

### Example Question #2 : Understanding Amplitude And Period

A wave has a period of . What is its frequency?

**Possible Answers:**

**Correct answer:**

The relationship between frequency and period is .

Plug in our given value:

### Example Question #2 : Understanding Amplitude And Period

A certain type of radiation on the electromagnetic spectrum has a frequency of . What is the period of this radiation?

**Possible Answers:**

**Correct answer:**

The relationship between frequency and period is:

We are given the frequency in the question. Using this value, we can solve for the period.

### Example Question #4 : Understanding Amplitude And Period

What is the frequency of a wave with a period of ?

**Possible Answers:**

**Correct answer:**

The relationship between frequency and period is:

Frequency is simply the reciprocal of period.

### Example Question #3 : Understanding Amplitude And Period

A saxophone plays a note with a wavelength of . What is the period of the sound?

**Possible Answers:**

**Correct answer:**

The relationship between wavelength, frequency, and velocity is:

Frequency is the inverse of period, allowing us to substitute into the velocity equation.

We are given the speed of sound and the wavelength. Using these values, we can solve for the period.

### Example Question #4 : Understanding Amplitude And Period

A bird chirps times per second. What is the period of the chirping?

**Possible Answers:**

There is insufficient information to solve

**Correct answer:**

The problem gives us a frequency in chirps per second. This is the same as as a "chirp" has no dimensional value.

Period is given by the reciprocal of frequency.

Using our known frequency, we can solve for the period.
