17.2-17.4(haillie, trenz)

How is the vibration of the source related to the waves frequency?

• increasing the frequency of a wave decreases its wavelength 
• A wave's frequency equals the frequency of the vibrating source production the wave 
• the more energy a wave has, the greater the vibration is

If you increase the frequency of a wave what will happen to its wavelength 

• stay the same 
• increase 
• decrease

how do find speed 

• wavelength/frequency  
• wavelength X frequency  

Destructive interference occurs when two or more waves combine to produce a wave with a smaller displacements 

• true 
• false 

wavelength is 

• The lowest part of a transverse wave
• The highest part of a transverse wave
• The distance between a point on one wave and the same point on the next cycle of the wave
• A wave that occurs at the surface between two mediums.

An antinode is a point where a crest or through occurs midway between two nodes 

• true
• false 

what is periodic motion 

• any motion that repeats at regular time intervals
• A wave in which the vibration of the medium is parallel to the direction the wave travels
• a disturbance in matter that carries energy from one place to another
• An area of a longitudinal wave where the particles of the medium are close together

reflection is an area of a longitudinal wave where the particles of the medium are spread out

• false 
• true 

refraction is an area of a longitudinal wave where the particles of the medium are spread out

• true 
• false 

Diffraction is the bending of a wave as it moves around an obstacle or passes through a narrow opening 

• true 
• false
