Facts of Physics: Refraction & Reflection

Flashcards for Physics lecture notes on Refraction & Reflection.

Reflection

The return of a wave back into its original material.

Refraction

The bending of a wave as it changes materials due to a change in speed.

Diffused Reflection

Reflection from a rough surface in many directions.

Incident Ray

The ray that shines on the mirror.

Reflected Ray

The ray that reflects from the mirror.

Angle of Incidence

The angle between the normal and the incident ray.

Angle of Reflection

The angle between the normal and the reflected ray.

Law of Reflection

States that the angle of incidence and the angle of reflection are equal.

Plane Mirrors

Flat-shaped mirrors.

Virtual Image

An image that appears to be in a location where light does not really reach.

Object Distance

The distance between the mirror and the object.

Image Distance

The distance between the mirror and the image.
