What is compression?
A force that tends to shorten or squeeze something, decreasing its volume.
What is the electromagnetic spectrum?
A range of wave lengths and or frequencies.
What is a longitudinal wave?
Wave in which partials of the medium vibrate in the direction of the wave.
What is refraction?
The bending of a wave when it enters through a different medium.
What is destructive?
Wave type out of phase that decreases the combined wave.
What is a concave lens?
A lens where the middle is curved inward. (Objects appear smaller)
What is the order of the electromagnetic spectrum?
Gamma, X-Ray, Ultraviolet, Visible light, Infrared, and Radio.
What is Medium?
An intervening substance through which something is transmitted or carried on.
What is diffraction?
The bending of a wave around the edge of an object.
What is Transverse?
Wave in which partials of the medium vibrate at right angles in the direction of the wave.
What is Amplitude?
Maximum Distance the partials of a medium move from there resting positions. (When a wave comes through.)
What is Energy?
Ability to change causes in matter.
What is a radio wave?
What is sound?
Transfer of energy from a vibrating object in longitude waves that travel through matter.
What's a trough?
The lowest part of a wave between crests.
What is convex lens?
A lens where the middle is curved outward. (Objects look bigger)
What is frequency?
The # of complete cycles in one second. (Crest to crest and trough to trough.)
What is Rarefaction?
A decrease in density and pressure in a medium when caused by the passage of a wave.
What is interference.
What is a wavelength?
Distance between two points of adjacent waves.
The ability of an object to vibrate by absorbing energy at its natural frequency.
What is light?
Electromagnetic radiation that can be perceived by the human eye.
What is reflection?
The bouncing of light from a surface.
What is constructive?
Wave type in phase that builds.
What is a wave?
A disturbance or vibration, of a medium and moving through that medium.
