Q: When sound wave is refracted from air to water what will remain unchanged 1 Frequency 2 Wave length 3 Wave Velocity 4 Both Wave length and velocity?

Write your answer...

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

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

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

velocity=frequency×wavelength therefore wavelength= velocity ÷ frequency

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 = frequency x wavelength

velocity = frequency / wavelength, I believe.

velocity cause Velocity= wavelength X frequency

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.

Velocity/wavelength=frequency

Velocity equals frequency times wavelength

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

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

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.

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

Unchanged, as long as they stay balanced.

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.

velocity increases

Frequency.

wavelength = velocity / frequency

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

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

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

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