How do you know the speed of an electromagnetic wave in a vacuum?
The speed of electromagnetic waves in a vacuum is the same as the speed of light (which is, in itself an electromagnetic wave). It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
How is waves speed related to its wavelength and frequency?
As long as the wave stays in the same medium, the product of its wavelength and frequency is always the same number ... its speed.
What similarities do the waves of all colours of light share?
They are all waves, they have wavelength, they all have the same speed which is the speed of light, they all consist from photons.
What is it that all electromagnetic waves do the same?
All electromagnetic waves travel at the same speed in a vacuum -- the speed of light.
Which travels faster radio waves or microwaves?
-- Microwave ARE radio waves.-- All electromagnetic waves travel at the same speed, including radio, microwaves,heat, infrared radiation, light, ultraviolet radiation, X-rays, gamma rays, and allthe others.
Do micro waves move faster than the radio waves?
Microwaves ARE radio waves, and they move with the same speed as all other electromagnetic waves.
How do the speeds of various electromagnetic waves compare?
They all move at the speed of light. Wavelength varies, but the speed is the same.
What is the speed of radio waves with a wavelegnth of 4.2m?
The speed of any electromagnetic waves (and that includes radio waves) in a vacuum is always the same - approximately 300,000 km/second. The wavelength is irrelevant.

As long as the wave stays in the same medium, the product of its wavelength and frequency is always the same number ... its speed.
In what situation is the speed of waves of red light exactly equal to the speed of blue light?
speed of light is always the same, regardless of frequency/colour.
What similarities do the waves of all colours of light share?
They are all waves, they have wavelength, they all have the same speed which is the speed of light, they all consist from photons.
Different kinds of energy waves that move at the speed of light in a vacuum make up the?
In any substance, all electromagnetic waves travel at the same speed that light travels through that substance.
What is it that all electromagnetic waves do the same?
All electromagnetic waves travel at the same speed in a vacuum -- the speed of light.
Which travels faster radio waves or microwaves?
-- Microwave ARE radio waves.-- All electromagnetic waves travel at the same speed, including radio, microwaves,heat, infrared radiation, light, ultraviolet radiation, X-rays, gamma rays, and allthe others.
Why do light rays move faster than gamma rays?
They don't. Both are electromagnetic waves, so they both move at the so-called "speed of light", which is 300,000 km/second. At least, that's their speed in a vacuum, which is the same for all types of electromagnetic waves.
What moves faster an x ray or a microwave?
All electromagnetic waves move at the same speed, at least in vacuum. X-rays and microwaves ... as well as radio, infrared, ultraviolet, heat, and visible light ... are all electromagnetic waves, and travel at the same speed.
