Transverse wave
- Mathematics and experiments show that light is a transverse wave – the electric and magnetic field vectors point in directions that are perpendicular to the direction of motion of the light wave (and as it turns out, they also rare always perpendicular to each other).
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.
Light as a Wave. Reflection and Refraction. All waves exhibit both reflection and refraction properties. When a wave moves from one medium into another, its direction of propagation changes; this is termed refraction.

The electromagnetic spectrum describes all of the kinds of light, including those the human eye cannot see. In fact, most of the light in the universe is invisible to our eyes. The light we can see, made up of the individual colors of the rainbow, represents only a very small portion of the electromagnetic spectrum. Other types of light include rad...
Light travels in waves, much like the waves you find in the ocean. As a wave, light has several basic properties that describe it. One is frequency, which counts the number of waves that pass by a given point in one second. Another is wavelength, the distance from the peak of one wave to the peak of the next. These properties are closely and invers...
To study the universe, astronomers employ the entire electromagnetic spectrum. Different types of light tell us different things. Radio waves and microwaves, which have the lowest energies, allow scientists to pierce dense, interstellar clouds to see the motion of cold gas. Infrared light is used to see through cold dust; study warm gas and dust, a...
Quick Facts: Electromagnetic Spectrum. Also known as: Electromagnetic radiation. Type: Radio, microwave, infrared, visible, ultraviolet, X-ray, and gamma ray. Size: We can describe light waves in terms of wavelength, or distance from one wave peak to the next.
What are light waves? 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...

In all of these cases, light is modeled as traveling in straight lines called rays. Light may change direction when it encounters objects (such as a mirror) or in passing from one material to another (such as in passing from air to glass), but it then continues in a straight line or as a ray.
