Reflection of Light

Answer

The return of light into the same medium after striking a surface is called reflection of light. Example: When light from a torch falls on a mirror, it bounces back into the air, allowing us to see ob

Answer

1. The angle of incidence is equal to the angle of reflection (∠i = ∠r). 2. The incident ray, reflected ray, and normal at the point of incidence all lie in the same plane.

Answer

Regular reflection occurs on smooth surfaces like mirrors, producing parallel reflected rays in a fixed direction. Irregular reflection occurs on rough surfaces like walls, scattering light in differe

Answer

Incident ray: Light ray striking a reflecting surface. Normal: Perpendicular drawn to the surface at point of incidence. Angle of incidence: Angle between incident ray and normal, denoted by 'i'.

Answer

When a light ray is incident normally (perpendicularly) on a plane mirror, the angle of incidence = 0°, so angle of reflection = 0°. The ray reflects back along the same path (retraces its path).

1. Virtual (cannot be obtained on screen) 2. Erect/upright 3. Same size as object 4. Laterally inverted (left appears right) The image is located at the same distance behind the mirror as the object i

Answer

The interchange of left and right sides in the image of an object in a plane mirror is called lateral inversion. Example: A ring on your left hand appears on the right hand in your mirror image. The w

Answer

When two mirrors are placed parallel to each other, infinite images are formed. This happens because the image formed by one mirror acts as an object for the other mirror, creating a continuous proces
