ray model

light is in

rays (straight lines)

light travels in STRSIGHT lines until it

Strikes an object

Ray diagrams are drawings that show the path of light when it

Leaves the source

transmitted

light goes through

reflected

Light bounces off

Absorbed

Light is taken into the substance

Transparent

transmits all incident light

Example of ytansparent material

Clear glass/plastic

Translucent material is

When some of the incident light is transmitted and the rest is reflected or absorbed

Example of translucent light

Frosted glass

Opaque materials are WHEB

All incident light is reflect/absorbed

Example of opaque materials

Wood, mirror

mirrors are

Polished surfaces with reflect lifht to produce an image

Image

Copy of an object using light

Reflection

Light bouncing back from a surface

Plane mirror means

Flat mirror

Front part of a mirror is

A sheet of glass

Back part of a mirror is

Reflective silver or aluminum

Point of incidence

Spot where incident rat strikes the surface

Incident ray is

A ray of light coming from source to surface

Reflected ray is

Light that bounces off the surface

Normal is

A perpendicular like to the surface of the POI

angle is incidence is

Angle between the incident ray and the normal

Angle of reflection is

Angle between the reflected ray and the normal

Angle of incidence is ___ to the angle of reflection

Equal

light is in

rays (straight lines)
