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 rays that reflect follow the law of reflection. The law of reflection states that the angle of reflection * is equal to the angle of incidence. Light rays that pass through an interface are transmitted rays. These rays bend. This bending is called refraction.
When we do that, we narrow down all the possible directions of the light wave motion to a single line, which we call a light ray. This is a directed line that originates at the source of light, and ends at the observer of the light:
Light Waves - BBC Bitesize. 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,...

All waves are known to undergo reflection or the bouncing off of an obstacle. Most people are very accustomed to the fact that light waves also undergo reflection. The reflection of light waves off of a mirrored surface results in the formation of an image. One characteristic of wave reflection is that the angle at which the wave approaches a flat ...
All waves are known to undergo refraction when they pass from one medium to another medium. That is, when a wavefront crosses the boundary between two media, the direction that the wavefront is moving undergoes a sudden change; the path is "bent." This behavior of wave refraction can be described by both conceptual and mathematical principles. Firs...
Reflection involves a change in direction of waves when they bounce off a barrier. Refraction of waves involves a change in the direction of waves as they pass from one medium to another. And diffractioninvolves a change in direction of waves as they pass through an opening or around an obstacle in their path. Water waves have the ability to travel...
When light waves reflect at the top and bottom interfaces of a thin layer of material, an interference effect will occur. This phenomenon is known as thin-film interference. Light will reflect off of both the top and bottom surfaces of the thin film.
