Chapter 23 - Waves Flashcards
Which type of wave requires a medium to travel?
Mechanical waves
Which type of wave does not require a medium to travel?
Electromagnetic waves
What is the part of the longitudinal wave where particles are crowded together?
Compression
what is the part of a longitudinal wave in which particles are spread out?
rarefaction
What is the lowest point on a transverse wave?
trough
What is the highest point on a transverse wave?
crest
What type of wave is a combination of a transverse and longitudinal wave in the middle of 2 media?
a surface wave
if a wave has a higher frequency, it has _____ energy
more
If a wave has a larger amplitude, it has _____ energy
more
if a wave has a longer wavelength, it has _____ energy
lower
if a wave has a shorter wavelength, it has _____ energy.
more
What is it called when a wave bounces off a surface that it can’t go through?
Reflection
What is the bending of a wave as it moves from one medium to another?
refraction
what is it called when a wave changes direction when it meets a surface, such as a corner or opening?
diffraction
What is it called when 2 or more waves collide and cause the waves to mess up each other
interference
what is the maximum distance that the particles on a wave vibrate from its rest position?
amplitude
The amount of waves in a given amount of time
frequency
the speed of a wave
wave speed
the wave’s particles move parallel to the direction of the wave
longitudinal wave
the wave’s particles move perpendicularly to the direction of the wave
transverse wave
how do waves transfer energy without transferring matter?
through vibrations
a physical environment in which waves can occur
medium
involves 2 parents creating 1 offspring; genetic variation is caused by the combination of 2 gametes
sexual reproduction
involves 1 parent cell dividing and forming 2 daughter cells
asexual reproduction
