Flashcards in Waves Deck (17):
A transverse wave is a wave vibrating at right angles to the direction of its propagation.
A compression wave is a longitudinal wave (such as a sound wave) propagated by the elastic compression of the medium.
The highest point of a wave.
The lowest point of a wave.
Compression is the action of compressing or being compressed.
Rarefaction is the reduction of an item's density, the opposite of compression. Like compression, which can travel in waves (sound waves, for instance), rarefaction waves also exist in nature. A common rarefaction wave is the area of low relative pressure following a shock wave.
The frequency of a wave is the number of waves passing a point in a certain time.
The amplitude of a wave is the distance from the center line (or the still position) to the top of a crest or to the bottom of a trough.
The distance between a point on one wave to the identical point on the next wave.
In the case of a water wave in the ocean, the medium through which the wave travels is the ocean water. In the case of a sound wave moving from the church choir to the pews, the medium through which the sound wave travels is the air in the room.
Electromagnetic waves are waves that are created as a result of vibrations between an electric field and a magnetic field.
A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.
How high or low the sound seems to be.
The bending of light because of a material.
Absorption is the process or action by which one thing absorbs or is absorbed by another.
Reflection is the throwing back by a body or surface of light, heat, or sound without absorbing it.
