Science chapter 11

Crest highest point of a transverse wave
Compressional wave A type of wave where the matter in the medium moves back and forth in the same direction that the wave travels
Amplitude A measure of the energy carried by a wave
Wavelength distance between one point on a wave and the nearest point just like it on the following wave
What do waves transfer through matter and space? Energy
Rarefaction The least dense region of a compressional wave
Refraction bending of a wave as it changes speed, moving from medium to another
Medium Any material that a wave transfers energy through
Wave A rhythmic disturbance that transfers energy through matter or space; exists only as long as it has energy
Trough lowest point of a transverse wave
Frequency Measures how many wavelengths pass a fixed point each second and is expressed in Hertz (Hz)
Transverse wave A type of wave where the matter in the medium moves back and forth at right angles to the direction the wave travels
Resonance ability of an object to vibrate by absorbing energy at its natural frequency
Standing wave A type of wave that forms when waves of equal wavelength and amplitude continuously interfere with each other
_____ is the lowest point in transverse waves Trough
A medium can be either _____,______,or,___ Solid,liquid,gas
Diffraction Describes the bending of waves around a barrier
The more energy a wave carries, the ______ its amplitude Larger
Interference Occurs when two or more waves overlap and combine to form a new wave
Constructive when two or more waves overlap and combine to form larger wave
Destructive when two or more waves overlap and combine to form a smaller wave
_________ waves have crests, and troughs Transverse
