Different Types of Spectra Any light source can produce a spectrum by scattering its light. The causes of various types of spectra can be derived from atomic theory. The spectra
Dispersion of Light The scientist Newton was the first to notice that sunlight, or white light, is a combination of different colours of light. He found that when white light
In 1928, the famous Indian scientist Sir Chandrashekhar Venkat Raman, or Sir C.V. Raman, passing monochromatic visible light rays through various liquids (e.g., benzene, toluene, etc.), observed that the incident
We know that when a light ray is refracted from a denser medium to a thinner medium, the refracted ray moves away from the perpendicular. As a result, the angle
Refraction and reflection are two basic properties of light. Clear images can be seen when light bounces off a surface, like in mirrors, a phenomenon known as reflection. On the
What is Refraction of Light? What is Refraction of Light: If light passes from one medium to another through the interface between two media, then, in general, the direction of
Reflection of Light The object that emits light is called a light source. Light sources can be of two types—a material that emits light by itself is called a self-emitting
Atomic Spectrum: Line Spectrum When an elemental gas or vapour is placed in a discharge tube at a pressure of a few millimetres of mercury and passed through it, the
WHAT IS SOUND? Sound is a type of energy produced by vibrating objects and propagated in waves via various mediums such as air, water, and solids. It is essential for
Table of Contents HISTORY OF QUANTUM NUMBERS The concept of quantum numbers developed in the beginning of the 20th century, alongside the development of quantum mechanics. In 1913, Niels
