THE RAY MODEL OFLIGHT
(virtual)
Light propogales in straight lines (light rays)
↳
shadows
↳ laser lights virtual
idea of light rays is used
to describe properties
of light: real
rays come from a source, hitting the mirror than reflect to
↳
reflection and refraction the observer, received rays trace back with the line of sight as
↳ form
image formation by and lenses virtual where the observer
perceives the
light
mirrors
rays come
How do we see an object? (this is where the image is formed)
↳
lightstarts from an object and
goes our in all
directions (light rays), the rays hit the eye images formed by plane mirrors are:
