Reflection and Laws of Reflection
Reflection is the phenomenon where a wave (like light, sound, or water) bounces back from a surface. In the case of light, reflection allows us to see our image in mirrors, and it plays a crucial role in various optical applications. The light rays will get reflected from the polished surface.
Laws of Reflection
There are two laws of reflection which are mentioned below:
- The incident ray, the reflected ray and the normal to the surface at the point of incidence all lie on the same plane.
- The angle of incidence will be equal to the angle of reflection.
Ray Optics – Definition, Formula, Applications
Ray Optics is the study of properties of light and optical instruments by assuming that light travels in a straight line. It is also known as geometrical optics, which deals with the geometry of light. Light always travels in a straight line, and the direction in which the light rays propagate is called the ray of light. It studies the principles and laws governing the propagation of light, particularly in the absence of wave effects such as interference and diffraction.
In this article, we will learn about ray optics, reflection, refraction, concave and convex mirrors, lenses, and formulas related to them.
