Example Questions
Example Question #18 : Understanding Wavelength And Frequency
A clarinet plays a note with a frequency of 
The relationship between wavelength, frequency, and velocity is:
We are given the speed of sound and the frequency, allowing us to solve for the wavelength.
Example Question #31 : Waves, Sound, And Light
A wave has a period of 
Frequency is equal to the reciprocal of the period:
Given the period, we can invert it to find the frequency.
Example Question #31 : Waves, Sound, And Light
The period of a wave is 
We need to know the wavelength in order to solve
We need to know the velocity of the wave in order to solve
Frequency is the reciprocal of period.
We are given the period, so we simply need to take the reciprocal to solve for the frequency.
Example Question #652 : High School Physics
A saxophone plays a B-flat at 
Remember that the velocity of a wave is always equal to the wavelength times the frequency:
All sound waves will travel with the same velocity, the speed of sound. Using this value and the given frequency, we can calculate the wavelength.
Example Question #32 : Waves, Sound, And Light
A flute plays a note with a frequency of 
Period is the inverse of frequency:
Given the frequency, we simply need to take the reciprocal in order to find the period.
Example Question #33 : Waves, Sound, And Light
A wave has a frequency of 
The relationship between frequency and period is 
Plug in our given value:
Example Question #34 : Waves, Sound, And Light
A wave has a period of 
The relationship between frequency and period is 
Plug in our given value:
Example Question #35 : Waves, Sound, And Light
A certain type of radiation on the electromagnetic spectrum has a frequency of 
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 #36 : Waves, Sound, And Light
What is the frequency of a wave with a period of 
The relationship between frequency and period is:
Frequency is simply the reciprocal of period.
Example Question #5 : Understanding Amplitude And Period
A saxophone plays a note with a wavelength of 
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.
