Question

explain ray diagrams

Answer 1

Hint: A ray diagram shows how light travels, including what happens when it reaches a surface. In a ray diagram, you draw each ray as a straight line with an arrowhead pointing in the direction that the light travels.

Complete step by step solution : A ray diagram is a presentation that traces the path that light takes in order for a person to view a point on the image of an object. On the diagram, rays (lines with arrows) are drawn for the incident ray and the reflected ray.
Light travels in straight lines within a medium (this means that light can change its direction upon a different medium)
Light has a direction of travel, it is often useful to indicate this with an arrow on your ray
A sharp real image (an image that can be displayed on a screen) is formed when all rays from one point on an object arrive at a unique point on the image
For situations involving multiple lenses or mirrors, the image formed from one of these components can act as the object for another one.

Note: Aside from these points u can draw an infinite number of ray in the ray diagrams. The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet light, X-rays and gamma-rays. Ray diagram helps to trace the path of the light for the person to view a point on the image of an object.
