States that the angle of incidence is equal to the angle of reflection
Law of reflection
States that the angle of incidence is equal to the angle of reflection. Law of reflection. In simple terms, the law of reflection means that when light hits a surface, it bounces back at the same angle it arrived.

The image of a distant object created when refracted light passes through air layers of different densities
Mirage
The image of a distant object created when refracted light passes through air layers of different densities. Mirage. A mirage is an optical illusion where light bends in the air, making objects appear displaced or distorted.

The opening at the center of the iris, through which light enters the eye
Pupil
The opening at the center of the iris, through which light enters the eye. Pupil. The pupil is the part of the eye that adjusts its size to control how much light enters, helping us see better in different lighting conditions.

A telescope that uses concave mirrors to reflect and focus light from distant objects
Reflecting telescope
A telescope that uses concave mirrors to reflect and focus light from distant objects. Reflecting telescope. A reflecting telescope is an instrument that uses mirrors to gather and focus light from stars and other celestial bodies.

A telescope that uses convex lenses to focus light from distant objects
Refracting telescope
A telescope that uses convex lenses to focus light from distant objects. Refracting telescope. A refracting telescope is a device that uses lenses to gather and focus light from faraway objects to make them appear closer and clearer.

The reflection that occurs when parallel light rays hit a smooth surface and every ray is reflected at the same angle
Regular reflection
The reflection that occurs when parallel light rays hit a smooth surface and every ray is reflected at the same angle regular reflection. Regular reflection is when light bounces off a smooth surface in a uniform direction, like a mirror.

Occurs when light hits the boundary between two materials but is reflected back
Total internal reflection
Occurs when light hits the boundary between two materials but is reflected back. Total internal reflection. It is when light completely reflects inside a material instead of passing through, like light bouncing back into water from its surface.
