Reflection, refraction and diffraction are all boundary behaviors of waves associated with the bending of the path of a wave. The bending of the path is an observable behavior when the medium is a two- or three-dimensional medium. Reflection occurs when there is …

reflection: the property of a propagated wave being thrown back from a surface (such as a mirror) refraction: Changing of a light ray’s direction when it passes through variations in matter. index of refraction: For a material, the ratio of the speed of light in vacuum to that in the material.

Aug 10, 2016 · In the case of visible light, the separation of wavelengths through diffraction results in a rainbow. A spectrometer uses diffraction (and the subsequent interference) of light from slits or gratings to separate wavelengths.

There are essentially four possible behaviors that a wave could exhibit at a boundary: reflection (the bouncing off of the boundary), diffraction (the bending around the obstacle without crossing over the boundary), transmission (the crossing of the boundary into the new material or obstacle), and refraction (occurs along with transmission and ...

We saw that light waves have the capability of changing the direction of the rays associated with it through diffraction. We now consider another way that such a direction change can occur. This process, called refraction, comes about when a wave moves into a new medium.

Reflection is a wave phenomenon that changes the direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Transmission permits the passage of wave, with some or none of the incident wave being absorbed.

Mar 27, 2021 · The angle of incidence (i) is equal to the angle of reflection (r). Refraction. When a wave passes from one medium to another (such as from air to glass) the direction of the wave changes. This change in direction is called refraction. As with reflection we have an angle of incidence, but instead of an angle of reflection we have and angle of ...

Diffraction is an interference effect caused by reflective strips separated by a non-reflective strip. • Compact discs have information coded along narrow, reflective lines.
