It is a mirror with a surface that is either concave or convex and forms a portion of a true sphere.

It is a type of surface reflectance often described as a mirror-like reflection of light from the surface when the angle of incidence is equal to the angle of reflection.

It is simply defined as the bending of light.

It is a ray of light that bounces back as it approaches a smooth polished surface, like on the plane mirror

It is the bouncing back of light.

It is a discipline of physics concerned with the behavior and properties of light, as well as its interactions with matter and the design of equipment that uses or detects it.

It is a ray that is incident at 90 degrees to a surface, perpendicular or normal to the surface.

It is a transparent piece of material that is been formed to bend light rays in a given way as they pass through it, whether that means causing them to converge at a specific point or diverge as if from a specific point.

It is a ray that strikes the surface separating the two optical media.

He was an Arab Andalusian Muslim scholar, mystic, poet, and philosopher, extremely influential within Islamic thought. He was considered to be the “Father of Modern Optics”.

It refers to the number of waves that pass a fixed point in unit time.

It is the reflection of light from a surface such that an incident ray is reflected at many angles.

The angle between the reflected ray and the normal.

The angle between the incident ray and the normal is known as the angle of incidence.
