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.
開啟
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
