Best Answer

If there is no relative velocity between source and listener, there will be no change in frequency.

Q: When both source and listener move in the same direction with a velocity equal to half the velocity of sound the change in frequency of the sound as detected by the listener is?

the velocity of a wave is given by frequency*its wavelength

It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't.

Velocity (speed and direction) Wavelength (frequency)

The velocity of a wave is the product of frequency and wavelength,such that: V=fλ

A change in velocity constitutes a change in direction because velocity includes direction.

the velocity of a wave is given by frequency*its wavelength

Speed in a given direction is velocity.

The wave speed is (frequency) x (wavelength) = 342 meters per second.We can't describe its velocity, because we don't have any informtion aboutits direction, beamwidth, etc.

Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.

velocity = frequency × wavelength frequency = velocity / wavelength f= 100 /20 f= 5 Hz

Frequency = Velocity divided by wavelength. So if frequency is doubled that means velocity is doubled but the wavelength is halved. You can see this by keeping wavelength a constant : If Frequency =1 and Wavelength= 1 1= Velocity/1 Velocity=1 If Frequency =2 and Wavelength= 1 2= Velocity/1 Velocity =2 OR keeping Velocity constant: If Frequency =1 and Velocity= 1 1= 1/Wavelength Wavelength =1 If Frequency =2 and Velocity= 1 2= 1/Wavelength Wavelength=1/2

Velocity (speed and direction) Wavelength (frequency)

Speed in a given direction is called velocity.

The velocity of a wave is the product of frequency and wavelength,such that: V=fλ

Velocity equals frequency times wavelength. If frequency is constant, velocity is proportional to wavelength; one increases at the same rate as the other.
