What happens when light is refracted?

When light is refracted, it changes direction as well as its velocity. However, it doesn’t change its wavelength and frequency


How is frequency related to velocity?

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


Can you find volocity if you have wavelength and frequency?

Wavelength = Velocity / Frequency So, Velocity = Wavelength * Frequency


Formula for wavelength?

velocity=frequency×wavelength therefore wavelength= velocity ÷ frequency


If the frequency is doubled then for waves what would be the wavelength and vlocity?

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


How is the velocity of a wave calculated?

velocity = frequency x wavelength


What is the formula of wave velocity?

velocity = frequency / wavelength, I believe.


The product of the wavelength times the frequency of a wave is its?

velocity cause Velocity= wavelength X frequency


What is the relationship between velocity and frequency?

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


How does velocity vary with wavelength if frequency is the same?

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


What is the relationship among wavelegnth and wave velocity?

Velocity/wavelength=frequency


What is the relationship between the frequency and the wavelength and angular velocity of electromagnetic wave?

Velocity equals frequency times wavelength


What is the formula for the velocity of a wave?

One formula is:speed (of the wave) = frequency x wavelength


What is the velocity of a wave with a frequency of twelve Hz and a wavelength of three m?

The velocity of a wave is wavelength x frequency. velocity = 3m x 12/s = 36m/s


If the frequency is 2 cycles per second then what is the wavelength?

It is not possible to answer this question numerically because the velocity of the wave also needs to be known. The three following equations are equivalent. velocity = wavelength x frequency wavelength = velocity / frequency frequency = velocity / wavelength The correct unit for frequency is Hz (Hertz) although this is the same as the old "cycles per second". Wavelength is measured in metres and velocity in metres/second.


What is the correct expression for the relationship between frequency and wavelength for a wave?

velocity of light in vacuum=(frequency)*(velocity of light in air)


How is velocity affected when balanced forces acted on an object?

Unchanged, as long as they stay balanced.


You can determine the velocity of a wave when given the frequency and the?

You can use the equation v=fw. that is velocity (in meters per second) equals the frequency (in hertz) times the wavelength (in meters). so you can find the velocity of a wave with the frequency and the wavelength.


Frequency of a wave increases and the wavelength stays the same what happens to velocity?

velocity increases


Wave velocity is proportional to what?

Frequency.


What is the relationship betwen wavelength and frequency?

wavelength = velocity / frequency


Does the velocity of sound change with medium?

Of course,velocity and wave length change.But frequency is constant.


How do wavelength and periods relate?

Wavelength*Frequency = Velocity of the wave. or Wavelength/Period = Velocity of the wave.


How does increasing the wavelength affect the frequency?

velocity = frequency x wavelength so assuming velocity remains constant (which it should) increasing the wavelength will result in a decrease in frequency.


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?

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