Question

what is ray of light​

Answer 1

Answer:

$\huge\mathfrak\pink{==>}$A light ray is a line (straight or curved) that is perpendicular to the light's wavefronts; its tangent is collinear with the wave vector. Light rays in homogeneous media are straight. They bend at the interface between two dissimilar media and may be curved in a medium in which the refractive index changes.

$\huge\mathfrak\blue{==>}$Ray of Light : A line drawn in the direction of propagation of light is called a ray of light. 2. Beam of Light : A group of rays of light emitted by a source of light is called a beam of light. A light beam is of three types.

Explanation:

$\huge\mathfrak\pink{==>}$Ray of light Beam of light

1. Ray of light is the path along which the light travels Many rays of light form a beam of light

2. A ray of light can be emitted from any source in any direction A beam of light can be emitted from a Laser source

3. A ray of light contains only one photon A beam of light contains multiple photons
