Waves
This type of wave needs a medium
Mechanical wave
The distance from the resting position to the crest (or trough) is called what?
Amplitude
True or false: Light travels in straight lines.
True
This is where the particles of a longitudinal wave are crowded together
Compression
This is the bouncing back of light or sound waves
Reflection
X-rays, microwaves, and light waves are examples of these types of waves
Electromagnetic
This is any substance through which a wave can travel
Medium
This is The distance from crest to crest, or from trough to trough
Wavelength
This is where the particles of a longitudinal wave are spread apart
Rarefaction
This is the bending of a wave as it passes from one medium to another
Refraction
This is any disturbance that transmits energy through matter or empty space
Wave
This is the highest point of a transverse wave
Crest
This is the number of waves produced in a certain amount of time
Frequency
What does it mean if a light wave has a higher amplitude? What if a sound wave has a higher amplitude?
The light is brighter. The sound is louder.
Where do sound waves travel fastest? Where do light waves travel fastest?
Sound waves = medium is a solid
Light waves = vacuum
This is a wave where the particles vibrate parallel to the direction of the wave; wave parts are called compressions and rarefactions
Longitudinal wave
This is the lowest point of a transverse wave
Trough
This is the maximum distance the particles of a wave vibrate from resting position
What is amplitude
Sound waves are examples of what type of wave?
Mechanical or longitudinal
Explain what makes an object appear blue.
Blue light waves are reflected off of the object while all other colored light waves are absorbed
This is a wave where the particles vibrate perpendicular to the direction of the wave; made up of crests and troughs
Transverse wave
This is what electromagnetic waves can travel through. Another word for empty space
Vacuum
If you increase the wavelength, what happens to the frequency?
Frequency decreases
Light waves are examples of what type of wave?
Transverse or electromagnetic
This is the word we use to measure frequency
Hertz (Hz)
