Mar 13, 2024 · Light waves, or electromagnetic waves, are transverse waves. They are vibrations that occur in both the electric and magnetic fields. Electromagnetic waves travel at the speed of light through a vacuum—meaning they do not need a medium in which to travel in.
Define the electromagnetic spectrum, and describe it in terms of frequencies and wavelengths. Describe and explain the differences and similarities of each section of the electromagnetic spectrum and the applications of radiation from those sections.
Aug 29, 2023 · The part of the electromagnetic spectrum with the longest wavelength and lowest frequency is radio. The portion with the shortest wavelength and highest frequency is gamma radiation. Visible light, which is the portion of the spectrum that we can see, is roughly in the middle.
May 24, 2024 · We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.
Oct 21, 2024 · The entire electromagnetic spectrum, from the lowest to the highest frequency (longest to shortest wavelength), includes all radio waves (e.g., commercial radio and television, microwaves, radar), infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

Nov 14, 2014 · Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons , each traveling in a wave-like pattern at the speed of light .
Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they...
