• ## 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…

• ## Uses and applications of total internal reflection

When the angle of incidence becomes larger than the critical angle, no refraction occurs. The entire light is reflected back into the denser medium. This is known as a total internal reflection of light. Prisms, binoculars, and optical fibers are…

• ## Image formation by convex and concave lens ray diagrams

How convex and concave lens work? In mirrors, images are formed through reflection but lenses form images through refraction. This is explained with the help of ray diagrams as follows: Image formation by convex lens ray diagrams Image formation in…

• ## 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…
