Jul 12, 2023 · In a vacuum, all forms of electromagnetic radiation—whether microwaves, visible light, or gamma rays—travel at the speed of light (c), which is the speed with which all forms of electromagnetic radiation travel in a vacuum, a fundamental physical constant with a value of 2.99792458 × 10 8 m/s (which is about 3.00 ×10 8 m/s or 1.86 × 10 5 mi/s). This is about a million times faster than ...

Jan 30, 2023 · Electromagnetic radiation can travel through empty space. Most other types of waves must travel through some sort of substance. For example, sound waves need either a gas, solid, or liquid to pass through in order to be heard. The speed of light is always a constant. (Speed of light : 2.99792458 x 10 8 m s -1)

A general equation relating the speed of light, frequency, and wavelength of electromagnetic radiation is given below: c = ν 𝝀. Where, 𝝀 = wavelength of the electromagnetic wave. Apart from frequency and wavelength, some other parameters are also used to categorise electromagnetic radiation. One of these parameters is the wave number.

X-Rays are a form of electromagnetic radiation, invisible to the human eye. Unlike visible light, x-rays have higher energy, higher frequency (and shorter wavelengths), which can penetrate most matter, including the body. Medical x-rays are used to generate images of tissues and structures inside the body.
