Question: how does a transverse wave move a medium?

Answer: moves the particles of the medium across or at a right angle to the the direction of the wave

==================================================

Question: how does a longitudinal wave move a medium?

Answer: moves the medium parallel to the direction in which the waves travel

==================================================

Question: what are four basic properties of waves

Answer: amplitude, wavelength, frequency, and speed

==================================================

Question: which wave property is directly related to energy

Answer: amplitude

==================================================

Question: which wave properties are distances?

Answer: wavelength

==================================================

Question: which wave property is measured relative to time

Answer: frequency and speed

==================================================

Question: what formula relates speed, wavelength and frequency?

Answer: speed= wavelength x frequency

==================================================

Question: two waves have the same frequency and wavelength. how do their speeds compare?

Answer: the speed would be the same

==================================================

Question: a waves frequency is 2 Hz and its wavelength is 4M. what is the waves speed?

Answer: speed = 2 HZ x 4 m or 8 m

==================================================

Question: what are 3 ways that waves change direction?

Answer: reflection, refraction, diffraction

==================================================

Question: how does a wave change direction when it bounces off of a surface?

Answer: reflection

==================================================

Question: how does a change in speed cause a wave to change direction?

Answer: refraction

==================================================

Question: what are two types of interference?

Answer: constructive and destructive

==================================================

Question: what determines the amplitude of the wave produced by interference?

Answer: whether or not is constructive or destructive interference

==================================================

Question: if wave a has the same amplitude as wave b what will happen when a crest of wave a meets a trough of wave b

Answer: the waves cancel completely

==================================================

Question: what is a standing wave?

Answer: a wave that appears to stand in one place even though it is really two waves interfering as they pass through each other

==================================================

Question: how do nodes and antinodes form in a standing wave?

Answer: nodes are always evenly placed along a wave. antinodes always occur halfway between two nodes
