Question | Answer |
wave | is a destebaence that transfers energy from place to place |
energy | as the ability to do work |
medium | material at which a wave travels |
mechanical wave | waves that require medium through which to travel |
vibration | is repeated back-and-fourth or up-and-down |
transverse wave | waves that move the medium at right angles to the direction in which the wave travels |
longitudinal wave | move the medium parallel to the direction in which the waves traveles |
compression | a part where all the coils are close together |
rarefaction | these parts were all the coils are spread out |
trough | lowest part of a transverse wave |
crest | highest part of a transverse wave |
wavelength | the distance between two corresponding parts of a wave |
amplitude | the maximum distance that the particles of the medium carrying the wave |
frequency | the number of waves that passes a certain spot in a certan amount of time |
hertrz | frequency is measured in units called ........ |
speed of wave | speed= wavelength+ frequency |
reflection | this interaction with a surface (seeing yourself in water) |
refraction | the bending of waves due to a change in speed |
diffraction | when two waves going in two different directions meet |
constructive interference | the interference that occurs when waves combine to make a wave with a larger amplitude |
destructive interference | an interference that occurs when waves combine and get smaller |
resonance | is an increase in the amplitude of a vibration |
standing wave | is a wave that appears to stand taller or in one place, but its the opposite |
