Reflection (physics) - Wikipedia
WebReflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light , sound and water waves .
Reflection | Definition, Types, Examples, & Facts | Britannica
WebApr 22, 2024 · reflection, abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums. At least part of the oncoming wave disturbance remains in the same medium. Regular reflection, which follows a simple law, occurs at plane boundaries.
16.1 Reflection - Physics | OpenStax
WebWhenever we look into a mirror or squint at sunlight glinting from a lake, we are seeing a reflection. How does the reflected light travel from the object to your eyes? The law of reflection states: The angle of reflection, θ r θ r, equals the angle of incidence, θ i θ i.
1.3: The Law of Reflection - Physics LibreTexts
WebSep 12, 2022 · Figure 1.3.1 1.3. 1: The law of reflection states that the angle of reflection equals the angle of incidence—θ r =θ i. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.
How Reflection Works in Physics - ThoughtCo
WebMar 12, 2019 · The law of reflection is used in physics to identify the location of an image that is reflected in a mirror. One consequence of the law is that if you view a person (or other creature) through a mirror and can see his eyes, you know from the way reflection works that he can also view your eyes.

10.2: Reflection - Physics LibreTexts
WebReflection. When a wave reaches the interface between two different media, typically some of the wave will bounce back into the original medium. This process is known as reflection. A familiar example of reflection is optical reflection in mirrors, where light waves reflect off a smooth surface.
Absorption and reflection (article) | Waves | Khan Academy
WebReflection happens when a wave bounces off of a boundary between two materials. Reflection depends on the type of wave, the wave’s frequency, and the material. Absorption happens when a wave loses energy as it transmits into a material. This can happen in a medium or at a boundary between two materials.
