Question 1: a wave that can only travel through matter

Answer:

mechanical wave Question 2: point in a standing wave of maximum displacement at which the interfering waves combine constructively

Answer:

antinode Question 3: point in a standing wave at which the interfering waves always cancel

Answer:

node Question 4: occurs when waves interfere and the resulting wave has an amplitude equal to the difference of the amplitudes of the original waves

Answer:

destrutctive interference

Question 5: the lowest point on a transverse wave

Answer:

trough Question 6: the bending of a wave caused by a change in its speed as it travels from one medium to another

Answer:

refraction

Question 7: distance between identical points on neighboring waves

Answer:

wavelength

Question 8: denser region of a longitudinal wave

Answer:

compression Question 9: a measure of the size of the disturbance of a wave; related to the energy that it carries

Answer:

amplitude Question 10: occurs when waves interfere and the resulting wave has an amplitude equal to the sum of the amplitudes of the original waves

Answer:

constructive interference Question 11: a wave in which the matter in the medium moves parallel to the wave (along the direction that the wave travels)

Answer:

longitudinal wave Question 12: repeating disturbance that transfers energy as it travels through matter or space

Answer:

wave

Question 13: the number of wavelengths that pass a fixed point each second

Answer:

frequency

Question 14: highest point of a wave

Answer:

crest

Question 15: matter through which a wave travels

Answer:

medium

Question 16: the bending of waves around an obstacle

Answer:

diffraction

Question 17: the amount of time it takes one complete wave to pass a point

Answer:

period

Question 18: a wave striking an object and bouncing off it

Answer:

reflection Question 19: the apparent change in frequency of a wave due to the motion of an observer relative to the wave's source OR the motion of the source of the wave relative to a stationary observer

Answer:

Doppler Effect

Question 20: the less-dense region of a longitudinal wave

Answer:

rarefaction

Question 21: the process of two or more waves overlapping and combining to form a new wave

Answer:

interferecne Question 22: wave in which the matter in the medium moves perpendicular (at right angles) to the direction of the wave

Answer:

transverse wave Question 23: a wave pattern that forms when waves of equal wavelength and amplitude, but traveling in opposite directions, continuously interfere with each other; it does not appear to be traveling

Answer:

standing wave
