Science Ch 10 Voc Flashcards
A repeating disturbance or movement that transfers energy through matter or space
Wave
Matter in which a wave travels
Medium
Wave for which the matter in the medium moves back and forth at right angles to the direction the wave travels, has crests and troughs
Transverse wave
A wave for which the matter in the medium moves back and forth along the direction that the waves travels
Compressional waves
The highest points on a transverse wave
Crest
Lowest points on a transverse wave
Trough
The least dense regions of a compressional wave
Rarefraction
Distance between one point on a wave and the nearest point just like it
Wavelength
The number of wavelengths that pass a fixed point each second, is expressed in hertz
Frequency
The amount of time it takes one wavelength to pass a fixed point
Period
A measure of the energy carried by a wave
Amplitude
The bending of a wave as it changes speed in moving from one medium to another
Refraction
The bending of waves around an obstacle, can also occur when waves pass through a narrow opening
Diffraction
Occurs when two or more waves overlap and combine to form a new wave
Interference
A wave pattern that forms when waves of equal wavelength and amplitude, but traveling in opposite directions, continuously interfere with each other
Standing wave
