Reflection and refraction

What stream to choose after 10th? Reflection The rapid change in the propagation direction of a wave that reaches the boundary between two mediums is known as reflection. At least a portion of the approaching wave disturbance is contained within the same medium.  Types of Reflection The different types of reflection are as follows: Regular […]

Reflection is derived from the Latin word reflectere, re: “back,” and flectere: “to bend,” so it means bending something back. Unless and until any obstacle or second medium arrives in the path of the light ray, the light travels in a straight line.  Law of Reflection  The reflection of light by a smooth surface is

Introduction  This law is usually referred to as Snell’s law. Snell’s law is outlined as the quantitative relation of the circular function of the angle of incidence to the circular function of the angle of refraction could be a constant, for the sunshine of a given color and the given try of the gallery. Snell’s

Whenever people open a window in a room, light comes in through it and spreads around the space. Do you know why this happens? This is due to the fact that light has a wave character and spreads around the room in all dimensions. Let’s look at Huygen’s Principle to get a better understanding of

Introduction Refraction is a natural phenomenon of bending light from one medium to another. The refraction occurs because of the change of speed of wave light on entering into another medium. This refraction is the cause of various other physical phenomena such as dispersion.  A prism is a well-polished optical element that is made to

The qualities of the medium affect the speed (increasing or decreasing) when light enters it. The optical density of the medium signifies the speed of electromagnetic waves. The optical density of the medium is defined as the tendency of atoms in a substance to recover absorbed electromagnetic energy. The speed of light depends on the

A prism is a homogeneous, transparent medium bounded by two plane surfaces inclined at an angle A with each other. These surfaces are called the refracting surfaces, and the angle between them is called the angle of prism (A). Let us consider the refraction of monochromatic light through a prism. Now, let i and e

Light scattering or dispersion occurs when white light is subdivided into various colour combinations due to refraction and Snell’s Law. White light looks white simply because it contains all the hues in the visible spectrum. Despite their proximity, the refraction index for each colour differs in non-vacuous objects. Because of these different indices, the wavelength

In optics, the critical angle is the incidence angle at which the angle of refraction is 90 degrees. The ratio of the velocity of a light beam in the air to the velocities of the specified medium is known as the refractive index. Because the critical angle is inversely proportional to the refractive index, it

The colour and texture are two elements of art that enhance the image feature. The colour is an important feature that beautifully transforms the image. The texture is the characteristic of an image that portrays the surface quality of the image. This study material covers the features of colour and texture in images or radiation.
