How does the speed of a photon compare with the speed of an electromagnetic wave?
Light can be considered as a wave, or as a particle. As a particle, the particles are called photons. As a wave, light is an electromagnetic wave. In either case, the speed of light (in a vacuum) is approximately 300,000 km/sec.
Why does light have a speed?
Light is an electromagnetic wave and, like all waves, it has a speed.
What is the speed of a light wave that travels at 900000000m in 3 seconds?
The speed of the light wave is 300,000,000 meters per second.
What is the the speed at which a wave travel through a medium?
the true answer is light speed
Why does an electromagnetic wave in space never slow down?
In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.
What equations tell us how fast a wave travels?
The speed of a wave can be determined by the equation: speed = frequency x wavelength. This equation relates the speed of a wave to its frequency and wavelength. Additionally, the wave equation, c = λf, where c is the speed of light, λ is the wavelength, and f is the frequency, can be used to determine the speed of electromagnetic waves in a vacuum.
The speed of a wave is its wavelength multiplied by its what?
The speed of light is fairly constant. 3.0X10^8 meters per second. Sounds' speed varies with conditions , but like light it is not changed by wavelength/frequency or amplitude.
What determines the frequency of an electromagnetic wave?
The frequency of an electromagnetic wave is determined by the speed of light divided by the wavelength of the wave. This relationship is defined by the equation: frequency = speed of light / wavelength.
What type of speed is light?
Light is a type of wave; it is not a type of speed.
What is the speed of any electromagnetic wave?
In a vacuum, any electromagnetic wave will move at the "speed of light", which is about 300,000 km/second.
What is the wave speed of vissible light?
"Wave speed" is meaningless. Do you mean wavelength? That's roughly 400-700 nm.
Can a wave travel faster than the speed of light?
No
