Hint: Light is an electromagnetic radiation composed of various bands, called an electromagnetic spectrum. For a light beam to travel, it needs a collection of different light rays. We will study about the beam of light and what a beam of light is composed of.
Complete answer:
The term Light refers to the electromagnetic radiation of any wavelength, whether visible or non-visible. It means that the gamma rays, the X-rays, the microwaves, and the radio waves, all are part of the light or electromagnetic spectrum. Like all the types of electromagnetic radiations, visible light propagates as waves. A light beam or a beam of light is defined as a directional projection of light energy being radiated from a light source.
The direction or the path along which light travels is called the ray of light. It is represented by a straight line and an arrow marked on it. A beam of light is defined as the group of rays of light travelling in a particular direction.
A beam of light can be of different types:
(i)Parallel beam of light: In a parallel beam of light, the rays from a distant source are parallel to each other.
(ii)Convergent beam of light: In a convergent beam of light, the rays proceed towards a particular point.
(iii)Divergent beam of light: In a divergent beam of light, the rays of light proceed away from the source point.
A beam of light is composed or made up of rays.
So, the correct answer is “Option A”.
Note:
A light beam or a beam of light is defined as a directional projection of light energy radiating from a light source. A ray of light is believed to be coherent light and focused in nature, such as polarized light, while a beam of light is considered as a light which is not focused.
