Amplitude Adventures
crest
Electromagnetic Wave
What is the lowest point on a transverse wave called
trough
What is a wave?
a repeating pattern of motion that moves energy
energy
Describe what the sound wave would look like for a sound a tiny mosquito makes
a low amplitude and a short wavelength
How do you measure wavelength for a longitudinal wave
from compression to the next compression
If a sound wave has a long wavelength and high amplitude what would it sound like
a low and loud sound
What is the height of the wave called?
amplitude
What happens during a compression on a longitudinal wave
particles move close together
What is diffraction?
The change in direction of a wave when it travels by the edge of an object or through an opening
What happens during rarefaction in a longitudinal wave?
particles move far apart
Do Mechanical waves need to travel through a medium?
Yes Mechanical waves must travel through a medium but electromagnetic waves do not.
If a transverse wave has a short wavelength and a high amplitude does it have more or less energy
more enery
What is transmission?
The passage of a wave through a medium
Which angle of motion does a longitudinal wave create
parallel
What is refraction?
The bending of light due to a change in medium
from crest to crest
What is absorption?
The transfer of energy by a wave to the medium through which it travels to
Explain why our pencil looks broken when we place it in a glass of water?
Refraction- light moving from the medium of air to the medium of water creates the optical illusion
What is Energy?
the ability to do work or cause a change
What are the main characteristic we would label on a transverse wave
crest, through, amplitude, wavelength, frequency
Describe how we see color
Objects reflect and absorb certain wavelength of light (color)
Which direction of motion do transverse waves have and what angle of motion does it create?
transverse waves energy moves up and down while it creates a perpendicular angle of motion
Explain how a rainbow happens
White light is refracted by raindrops bending the light and allows us to see all of the colors that make up white light
