How do you calculate the velocity of a wave?
The velocity of a wave can be calculated by multiplying the wavelength of the wave by its frequency. This equation is often denoted as v = λ * f, where v represents velocity, λ is the wavelength, and f is the frequency of the wave. Alternatively, the velocity of a wave can be found by dividing the distance the wave travels by the time it takes to travel that distance.
How is wave and velocity related?
Wave velocity is directly proportional to the frequency and wavelength of the wave. In general, wave velocity = frequency x wavelength. This means that as the frequency or wavelength of a wave increases, the velocity of the wave also increases.
What is it called when a straight line that represents a light wave?
A straight line that represents a light wave is called a ray. It is used to show the direction of light propagation in geometrical optics.
What is group velocity?
Group velocity is the velocity of the energy or information carried by a wave packet in a medium. It represents how fast the shape of the wave packet moves through the medium while maintaining its integrity. It can be different from the phase velocity of the individual waves that make up the packet.
Does the color of a laser affect the velocity of a light wave projected by the laser?
Colors are determined by the wavelengths but all wavelengths travel at the same speed. So no, colors do not affect the velocity of light.

If one of the waves represents infrared light and one wave represents visible light which wave represents visible light?
Without any other information, the one with a shorter wavelength/higher frequency will be visible light.

What is the difference between group velocity and phase velocity in a stationary wave on a string?
The velocity of a wave which maintains consatnt phase at all successive positions during propogation is known as wave velocity or phase velocity. The velocity of a group of waves which maintains constant poditions during the propogation is known as group velocity.
What is it called when a straight line that represents a light wave?
A straight line that represents a light wave is called a ray. It is used to show the direction of light propagation in geometrical optics.
What is Velocity of a light wave?
c= f x h
What is group velocity?
Group velocity is the velocity of the energy or information carried by a wave packet in a medium. It represents how fast the shape of the wave packet moves through the medium while maintaining its integrity. It can be different from the phase velocity of the individual waves that make up the packet.
When a light wave bends toward the normal what does that tell you about the velocity?
It decreases.
What represent the velocity of the light wave?
That means how fast it travels. ==================== c
Does the color of a laser affect the velocity of a light wave projected by the laser?
Colors are determined by the wavelengths but all wavelengths travel at the same speed. So no, colors do not affect the velocity of light.
When was velocity of a wave derived?
In order to find the velocity of a wave - you must know a few variables. The first variable that must be known is the wave-length, literally the length of said wave - and the second is the frequency often notated in Hz. Simply multiplying the frequency by the wavelength will create an answer.
Can phase velocity exceed the speed of light?
Yes, phase velocity can exceed the speed of light in certain mediums. This is known as superluminal phase velocity. However, this does not violate the principle of causality or the speed of light in vacuum as it is the group velocity, rather than the phase velocity, that carries the information in a wave.
