Difference between interference and diffraction in tabular form
The interference is the combination of the superposition of two or more waves that are in a point of space. The diffraction is the deviation suffering waves around the edges and corners that occurs when a portion of a wavefront is interrupted or…

Difference between Reflection and refraction in tabular form
Reflection and refraction are two different properties of light. The basic difference between reflection and refraction is that Reflection of light is the process in which light bounces back on striking the surface, while refraction of light is the process…

difference between fresnel and fraunhofer diffraction in tabular form
The basic difference between Fresnel and Fraunhofer diffraction is that in Fresnel diffraction the source of light and screen is at a finite distance from the obstacle, while in Fraunhofer diffraction if the source of light and screen is at…

Properties of light in physics
What is light? Light is a form of energy which is given by luminous objects. The Sun, bulb, candle, etc. are luminous objects. Other objects which do not give out light are called non-luminous objects. Light can pass through transparent…

Do interference effects occur for sound waves?
Yes, the interference effect occurs for sound waves despite the fact that sound waves are longitudinal waves. When two sound waves of the same frequency and same amplitude in the same direction superpose then the interference of sound waves occurs.…

examples of total internal reflection
Total Internal Reflection One of the qualities of any optically transparent material is the speed at which light travels within the material, i.e., it depends upon the refractive index n of the material. The index of refraction is merely the…

What are some examples of refraction of light?
“The process of bending of light as it passes from air into glass and vice versa is called refraction of light.”Mirage, bent pencil in a glass of water, rainbow, and sunset are some examples of refraction of light. Why does…

Types of Lenses
Lenses are the pieces of transparent material of which one or both sides are spherical. It is any transparent material having two surfaces, of which at least one is curved. Lenses refract light in such a way that an image…

types of optical fiber
Optical fibres are thread structure made of glass and plastic in which light travel by total internal reflection. optical fibres are hair size threads through which light passes by total internal reflection, There are three types of optical fibre:(1) Single…

Why diffraction grating have closely spaced rulings?
A diffraction grating is a glass plate having a large number of close parallel equidistant slits mechanically ruled on it.A diffraction grating is used to study the diffraction effects of light. Since the phenomenon of diffraction is found to be…
