Science Flashcards
(15 cards)
Frequency
the number of cycles a wave completes in a period of time; the number of times something happens in a period of time
Period
The length of time
Wavelength
the distance between one peak and the next on a wave
Crest
A the highest point of a wave
Trough
The lowest point of a wave
Medium
Is the part of the middle frequency of the wave
Amplitude
The height or strength of a wave
Longitudinal wave
a wave that occurs when the particles of a medium move parallel to the direction of the wave
Electromagnetic spectrum
the full range of frequencies of electromagnetic waves
Transverse wave
a wave that occurs when the particles of a medium are displaced perpendicularly to the direction of the wave
Compression
occurs when rocks are squeezed by external forces directed toward one another to put stress on the rock, acting to decrease its volume or shorten its dimensions
Rarefraction
A redemption of medium in a height wave
Reflection
to strike a surface and bounce back in the opposite direction (related word: reflection)
Refraction
An image shows the refracted image of a pencil in a glass of water.
Diffraction
The slight bending of light
