Best answer: What does the speed of an electromagnetic wave depend on?

Electromagnetic waves, like any wave, have a finite speed value which is dependent upon the properties of the medium through which it flows. … The speed of a wave is independent of its frequency and wavelength. A change in the frequency value will not result in a change in the speed value.

Does the speed of an electromagnetic wave depend on either the frequency or wavelength?

Hence the speed of electromagnetic waves depends both on frequency and wavelength. The speed of light is only independent of the intensity. Hence, option C is the correct answer. Note:When electromagnetic waves are passing through a medium, then their speed decreases.

Does the speed of a wave depend on frequency?

The speed of a wave is unaffected by changes in the frequency.

Why does the speed of a wave depend on the medium and not the frequency or wavelength?

If the wavelength decreases at the source, then the frequency increases because the speed has not changed. If the wavelength decreases due to a decrease in speed as the wave enters a different medium, then the frequency is not affected.

Is speed same for all electromagnetic waves?

Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum. We call this the “speed of light”; nothing can move faster than the speed of light.

Why does wave speed not depend on frequency?

Generally speaking, he speed a wave travels depends on its medium, not the amount of energy put into the wave. When a higher energy wave is introduced in the same medium, the speed the wave travels will not change.

On what factors speed of sound depends?

The speed of sound depends on the following factors: Density of air, Temperature, Humidity in the air as well the wind.

Does frequency increase with speed?

When frequency increases, speed increases and vice versa.

What determines the speed or velocity by a wave?

The velocity of a wave is equal to the product of its wavelength and frequency (number of vibrations per second) and is independent of its intensity. … All sound waves travel with the same speed in air regardless of their frequency.

Does the speed of a wave change in different mediums?

When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same.

What is the relationship between wave speed wavelength and frequency?

Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency.

What is the speed of an electromagnetic wave equal to?

The speed of any periodic wave is the product of its wavelength and frequency. v = λf. The speed of any electromagnetic waves in free space is the speed of light c = 3*108 m/s. Electromagnetic waves can have any wavelength λ or frequency f as long as λf = c.

What is the speed of each of the electromagnetic waves?

A large family of waves, each with a different wavelength range is called the electromagnetic spectrum (sometimes shortened to the EM spectrum). These waves all travel at the speed of light (300,000,000 metres per second) in a vacuum.

For what the speed of electromagnetic wave is not equal?

As the frequency and wavelength are changed, the speed of the electromagnetic wave changes. So, the speed of an electromagnetic wave is not same for ​all wavelengths and​ all frequencies in any medium. The velocity of an electromagnetic wave changes with change in medium.
