Answer:
- The light energy that allows us to see the objects that pass through a straight line is known as a ray of light—the reflection of light returns the beam that falls on the object’s surface.
- An incident ray is a beam of light that hits the surface by separating the two mediums through emission. It is a rectilinear light ray.
- The incident ray is either refracted or reflected to form an image. The angle between the incident ray is perpendicular to the surface of the angle of incidence.
- The angle of incidence is the inclination between the incident ray and the line perpendicular to the point of incidence.
