Speed of light

[lasarro]

Why do we use the speed of light to calculate the wavelength and frequency of electromagnetic waves, like radiowaves?

[nicolely2F]

EM waves typically travel at the speed 3x10^-8 m/s. Because light is a type of EM wave (and light waves are used in many scenarios), we call it the speed of light.

[alexfwang3g]

All EMR moves at the speed of light. Since the calculations utilized is regarding to a type of light, then naturally we should use 3x10^-8 m/s as well.

[Audrie Chan-3B]

The units from wavelength (m) and frequency (s) give velocity (m/s). The speed of light is essentially the velocity for these two factors because we are dealing with light waves.

Electromagnetic radiation moves at the speed of light

Because the calc is about a type of light, c= 3x10^-8 m/s is used.

[Anthony Hatashita 4H]

Any EMR has the same speed, we just call it the speed of light (c)

[stephaniekim2K]

Typically, if not mentioned, you use the speed of light in a vacuum.

[emwoodc]

EMR is the speed of light so we typically use it

[DMuth_1J]

The speed of light is a constant. No matter what kind of light or what variant of light, the wavelength multiplied by the frequency of a specific light sample being studied will always equal this constant 2.98x10^8 m/s

[Chantel_2I]

The speed of light can be used in regard to all types of electromagnetic radiation.

[chrischyu4a]

All electromagnetic radiation is light itself which is why they all travel at 3*10^8 m/s. The factors that distinguishes the types of EM waves are frequency and wavelength.

[Kevin Liu 1J]

speed of light is 2.998 x 10^8 m/s and this is utilized as waves are part of the light spectrum. Hope this helps!

[HuyHa_2H]

Electromagnetic radiation move at the same speed as the speed of light hence we use the constant 2.998 x 10^8 m/s for both subjects.

[RobertXu_2J]

Electromagnetic radiation travels at the speed of light, therefore we use the speed of light to calculate it. Light is a form of electromagnetic radiation, and the speed of light is really the speed of all these EM waves.
