What types of waves are pictured? - (ANSWER)A is a transverse wave and B is a longitudinal wave
Which of these choices most accurately describes how particles move in a transverse wave? -

Which part of the wave are the arrows pointing to? - (ANSWER)trough

Which of the following choices most accurately compares the amplitudes and wavelengths of the two
waves? - (ANSWER)The red wave has a greater amplitude because its height is greater than the height of
the blue wave. Both waves have the same wavelength because the distance between crests is the same.
They also have the same frequency because the wavelength and speed of each wave is the same.

Which type of behavior is depicted in the image? - (ANSWER)refraction
Refraction occurs when __________. - (ANSWER)a wave enters a new medium and changes its speed
Which of these describes a wave being reflected? - (ANSWER)The wave encounters some obstacle or
change in medium. The wave bounces off the surface and moves in a different direction, but at an angle
equal to the one at which it hit the surface.
Study the image of a wave moving from air to liquid.

Which of the following choices most accurately describes the behavior of the waves when they
encounter the liquid? - (ANSWER)The speed of the wave decreases when it enters the liquid, and the
wavelength decreases as a result. The wave also changes direction.
A(n) __________ energy wave is transferred through a substance as a series of compressions. -
(ANSWER)sound
A sound wave is moving with a frequency of 700 Hz. What is the period of this sound wave? -
(ANSWER)1/700 s
Sound waves are traveling through the air. Every ½ second, the sound waves pass a detector. Which of
the following choices correctly describes the period and frequency of these waves? - (ANSWER)The
period is ½ second, and the frequency is 2 Hz.
A disturbance that moves through a solid, liquid, gas, or a vacuum is defined as __________. -
(ANSWER)a wave, as long as matter is not being transported
