Example Question #661 : High School Physics
A wave has a frequency of 
The relationship between frequency and period is 
Plug in our given value:
Example Question #662 : High School Physics
A wave has a period of 
The relationship between frequency and period is 
Plug in our given value:
Example Question #663 : High School Physics
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 #664 : High School Physics
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 #665 : High School Physics
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.
Example Question #41 : Waves
A bird chirps 
There is insufficient information to solve
The problem gives us a frequency in chirps per second. This is the same as 
Period is given by the reciprocal of frequency.
Using our known frequency, we can solve for the period.
Example Question #666 : High School Physics
A spring oscillates back and forth with a period of 
Velocity is commonly described with respect to wavelength and frequency.
We are given the period and the wavelength. Period is simply the inverse of freqeuncy.
Using this, we can rewrite our original equation in terms of the period.
Now we can use the values given in the question to solve for the velocity.
Plug in our given values and solve.
Example Question #667 : High School Physics
A wave oscillates with a frequency of 
The equation for velocity in terms of wavelength and frequency is 
We are given the velocity and frequency. Using these values, we can solve for the wavelength.
Example Question #668 : High School Physics
A note is played in a gas (which is not a normal atmosphere). Inside of this gas, the note has a frequency of 
The relationship between velocity, frequency, and wavelength is:
Plug in the given information to solve:
Example Question #669 : High School Physics
An ambulance turns on its siren as it is driving away from you. What happens to the sound pitch?
The pitch will stay the same.
There is insufficient information to tell.
The pitch will sound higher.
You will be unable to hear the pitch.
The pitch will sound lower.
The pitch will sound lower.
The Doppler effect states that the frequency of sound increases as it approaches you and decreases as it goes away from you.
Since it is going away from you, the pitch of the sound will appear to get lower.
