Question

(e)
The path of light is:-
(1) Always a straight line
(ii) A curved line.
(iii) A zig zag line.
(iv) Depends on the medium.​

Answer 1

The path of light is always a straight line.

About pathway of light :

• The rectilinear propagation of light is the process of light traveling in a straight line without encountering any obstacles.

• Except at surfaces between two transparent materials, such as air and water or air and glass, where the light path bends, the course of light can be traced as straight lines. Light follows a straight path at all times.
• The path of light is represented by a ray, which is a straight line. A beam is made up of a series of parallel rays.

Answer 2

Answer:

Option(1) the path of light is always a straight line.

Explanation:

• A light beam will always move in a straight line. It always tends to go in a straight line because that is the fastest route between any two points.

• The ultimate straight line is the path of light. In addition to having the ideal path, light also has the best cruise control.

• It moves straight ahead at the speed of light, which is suitably named and equals 3 ×$10^8$ meters per second in a vacuum.

• The passage of light may be traced as straight lines everywhere except at interfaces between two transparent materials, such as air and water or air and glass, where the light path bends

• A ray, which is a straight line, is used to indicate the direction of light. A group of parallel rays makes up a beam.
