Sample Mind Map

Light behaves in fascinating ways when it interacts with various surfaces and mediums. It travels in straight lines and can reflect off surfaces, which is described by incident rays hitting a surface and reflected rays bouncing off.

Sample Mind Map

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
