What is a Wave?
A wave is a repeated pattern of motion that is caused by a _______?
Disturbance
The highest point of a wave
Crest
What type of wave moves in a perpendicular motion? (up and down)
Transverse waves
What is one example of an artificial source of light.
Flashlight, lamp, lightbulb, etc.
What is an example of a transparent material?
Anything clear or glass will work here.
Think: PARENTS are CLEAR about their expectations
A wave transfers ______ in the direction that the waves travel.
energy
The distance between two of the same points on a wave
Wavelength
The two main types of waves are mechanical and _________?
Electromagnetic
(2 answers!) The color of light with the longest wavelength is _______ and the shortest wavelength is _________.
Red, purple
True or False:
An example of a binary code is the Morse Code
True
A substance- solid, liquid, or gas- through which something can travel.
Medium
The distance from the crest or trough to the middle of the wave
Amplitude
Waves that need a medium to travel through them are called _______ waves.
Mechanical
Think MMMedium = MMMechanical
What is the process in which light bends as it passes from one medium to another.
Refraction (it's gonna bend!)
If all light is absorbed, we see what color because there are no wavelengths of visible light.
black
True or False: Waves can travel through space AND matter
True
The speed of a wave
Frequency
A type of wave that creates vibrations parallel to the direction of the wave.
Longitudinal waves
What type of wave is light?
Options: Transverse, longitudinal, Mechanical, Electromagnetic
Electromagnetic
The difference between a transverse wave and a longitudinal wave is: transverse waves cause particles to move (parallel/perpendicular) to the direction of the wave
Perpendicular
BONUS! This question is worth 800 points. (2 answers)
______ is how high or low a sound is.
______ is how fast or slow a sound is.
Amplitude, Frequency
The middle of the wave (there are two names for this, choose one)
Equilibrium or the line of origin
Waves that do not need a medium to travel through
Electromagnetic waves ex. visible light, x-rays, microwaves
Light waves travel in ________ lines.
Straight
What process is where light gets soaked in.
Absorption
