Light

refraction of light and critial angle

whenlight rays hit a n object - some of the light bounces back. we can see object when the reflected light enters our eyes.

color

can see 7 different thicknesses of the glass=different light speeds.Rainbow in natural light dispersion where water droplets acts as small prisms.

Reflection of light

Normal-perpendicular to the surface at the point of incidence

Angle of incident-angle between the incident ray and the normal.

Angle of reflected-Angle between the normal and the reflected ray

reflected ray-tye ray of light that reflects from the surface

Incident ray-the ray go light that hits the surface

Type of mirror

concave

convex

sight

limatations

magnifying glass,microscope,telescope,binocular,ultrasound scanning device,x-ray machine,MRI,Periscope

defects of vision-people with normal vision see sharp and clear images .cannot focus the eyeliner properly;they see thins blurry

Properties of light

refract-when change speed

Reflect-when hits a surface

Travels in straight lines

speed=3x10 8 m/sec

A from of energy
