Key Words
Light year- the distance light travels in a year (670,616,629 mph)
Frequency-The number of crests that pass a given point within one second
Energy- the ability to do work
Wave- a disturbance that measures energy
Medium- Matter that waves are traveling through
Mechanical Wave- waves that require a medium to pass through and whose speed depends on the medium.
Electromagnetic Wave- waves that do not require a medium and travel at the speed of light in a vacuum.
Wavelength- The distance between crests
Refraction- when light waves change direction as they pass from one medium to another.
Scattering- when light bounces off an object in a variety of directions.
Diffraction- the bending and spreading of waves around an obstacle.
Absorption- light wave being transmitted through an object and its energy being stored in that object
Reflection- when incoming light hits an object and bounces off.
Polarization- a measurement of the electromagnetic field's alignment.
Quasar- quasi-stellar radio source
