Diffraction
|
The bending of a wave when it goes around an object or through a gap, the amount of bending depends on the size of the gap and wavelength of the wave
|
|
Interference
|
The combining of two or more waves. either constructive or destructive.
|
|
Refraction
|
The bending of a wave as it enters a new medium at an angle and changes speed
|
|
Reflection
|
The bouncing back of a wave when it hits a barrier
|
|
Doppler Effect
|
The change in frequency that occurs when the source of a sound wave is moving relative to the observer, forward of moving object wavelength is small and frequency is high, behind the moving object wavelength is long and frequency is low
|
|
Constructive interference
|
When two waves combine and form larger waves
|
|
destructive interference
|
When two waves combine and form a smaller wave, or cancel each other out
|
|
Polarization
|
When light waves are limited by a filter to vibrating only in one plane
|
|
Non polarized light
|
Light waves moving in all directions
|
|
Polarized light
|
Light waves limited to one direction
|
|
reflection vs refraction
|
In reflection wavelengths bounce back off a barrier, where in refraction they continue on into a new medium at a new speed
|
|
diffraction example
|
Light bends as it passes between the water droplets of a cloud creating the clouds silver lining as the light is diffracted
