Because of bending of any wave, such as a light or sound wave, when it passes from one medium into another of different optical density.
No.
the velocity of a wave is given by frequency*its wavelength
The velocity of the wave
The speed the wave is traveling through space
The velocity of a point that moves with a wave at constant phase. Also known as celerity; phase speed; wave celerity; wave speed., wave velocity.
No.
the velocity of a wave is given by frequency*its wavelength
velocity = frequency x wavelength
Frequency of the a wave equals its velocity divided by its wavelength.
Energy of light photons is related to frequency as Energy = h(Planck's constant)* frequency Frequency = velocity of wave / wavelength So energy = h * velocity of the wave / wavelength
The velocity of the wave
The speed the wave is traveling through space
Wave velocity in general = frequency x wavelength As the velocity of the wave remains constant then frequency and wavelength are inversely related So as the wavelength becomes shorter then frequency becomes larger or higher
The velocity of a point that moves with a wave at constant phase. Also known as celerity; phase speed; wave celerity; wave speed., wave velocity.
How quickly the wave travels
C the distance between the top or bottom of a wave
Wave frequency can be calculated by dividing the speed of the wave (if we're talking about electromagnetic waves in vacuum, that would be the speed of light, c) by wavelength.
