Optics

To understand refraction and reflection of a plane wave on a plane surface using wavefront, there are some concepts that you need to be clear with. Refraction of a wave Waves change direction when they pass from one medium to another. This phenomenon is called refraction.  Refraction can occur in different types of mediums like […]

Definition of dispersion of light: The phenomenon in which the white light is splitting into seven different colours is known as the dispersion of light. The medium which conducts dispersion is called the dispersive medium.  What is a Prism? A prism is a solid geometric figure with equal and parallel rectilinear figures on all of

The splitting of white light into its constituent spectrum of colours when it travels through a glass prism is known as ‘dispersion of light’ .  At various frequencies and angles, white light splits into its constituent colours. Refraction is the bending of a ray when it passes at an angle from one medium into another

The shift in direction of a wave moving from one medium to another or from a gradual change in the medium is referred to as refraction in physics. Although light refraction is the most often observed phenomena, other waves such as sound and water waves are also subject to refraction. The change in wave speed

Light reflection occurs when the waves strike a surface or other boundary that does not absorb the radiant energy and reflects the waves away from the surface. The incident light wave is called the incident wave and the wave bouncing back from the surface is called the reflected wave. Visible white light directed at a

When you stand in front of a mirror, you can see your reflection. This reflection, located on the right side of the mirror, is correctly positioned since the top of your body represents the top of the mirror image.Your head and feet are not pointing away from you. When the left image in a mirror

When light flows through a transparent medium and bends, this is known as refraction. The optically rarer medium is one in which the velocity of light is higher, whereas the optically denser medium is one in which the velocity of light is lower. The refraction phenomenon is caused by differing light velocities in different media.

Everything that we can see in the world is processed by our minds as images. Real images and virtual images are the two forms of images. A virtual picture is one that is made by the divergence of light beams, whereas a real image is one that is formed by the convergence of light rays.

Raman Scattering, commonly referred as the Raman Effect, is a phenomena in which photons are scattered inelastically by matter, with the scattered photon’s frequency differing from that of the input photon. It implies that as the photon reaches the surface of the matter, the energy level and direction of the light will change. The effect occurs

Introduction  Reflection: The change in direction of a wavefront at an interface between two distinct media such that the wavefront returns to the medium from which it originated is known as reflection. The law of reflection says that for specular reflection the angle of incidence is equal to the angle of reflection. Mirrors are the
