Energy transferred through Space by electromagnetic. Electromagnetic Wave
a weave that moves perpendicular to the direction of the wave Transverse Wave
The height of a transverse wave from the center to the crest or trough. Amplitude
A wave that moves the medium in a direction parallel To the direction of the wave Longitudinal Wave
The distance between two corresponding parts of the wave. Wavelength
The number of complete waves that pass a given point in a certain amount of time. Frequency
When a wave bounces off a dense surface and changes direction. Reflection
When waves change direction or bend as they enter a new medium. Refraction
When waves spread out after passing through a narrow opening. Diffraction
How much light (or energy) passes through an object. Transmittance
When light (or energy) is taken in by an object and changed into another form. Absorption
