LIGHT: Geometric Optics

LENS

: a piece of transparent material that is shaped to cause light rays to bend in a specific way as they pass through it.

surface

A reflecting is a section of a sphere.

optical axis

The is the line of symmetry for the lens.

Convex

: Can be seen on the outside of the sphere.

Concave

: Can be seen on the inside of the sphere.

P

: Distance of the object from the mirror.

Q

: Distance of the image from the mirror.

parallel rays

The focal Point is the point where converge when after passing through a lens.

plane mirrors

The reflection on creates upright virtual images with the same magnification or size and distance as the object.

biconvex

The lens is a simple optical lens with two convex.

PERISCOPE

: An instrument for observations around or through object obstacle or condition that prevents direct line of sight.

KALEIDOSCOPE

: It manipulates and reflects when looking through the hole light filters to the glass.

Regular Specular

: The angle of incidence is equal to the angle of reflection.

F

: Focal length or the distance between the mirror and the focal point.

light rays

The are an approximation of the path of light where the straight lens is used to represent the motion of light waves.

Plane mirrors

have a flat surface and are known as "virtual "images.

Regular/Specular

The angle of incidence is equal to the angle of reflection

Irregular/Diffuse

A reflection of rough surfaces

Real

formed when rays converge

**^^Virtual

^^**formed when rays diverge

Upright

right side up

Inverted

Upside down

Concave

Can be seen on the inside of the sphere

Convex

Can be seen on the outside of the sphere

F

Focal length or the distance between the mirror and the focal point

P

Distance of the object from the mirror

Q

Distance of the image from the mirror
