Wave characteristics
True or False: Trough to Crest is a wavelength.
False
Medium
The substance that the wave travels through
Refraction
When light changes Direction slightly when it passes from one medium to another
Crest
The highest point on a wave
Compression
When the particles get really close together
Wavelength
The distance from any one point on a wave to the same point on the wave directly next to it
True or False: light can travel without a medium
True
DAILY DOUBLE
What pitch and loudness are and how they are measured
Pictures of measure of frequency and is measured in Hertz (Hz). Loudness is a measure of amplitude and is measured in decibels (dB).
Trough
The lowest point on a wave
Rarefaction
When the particles are spread apart
Wave Speed
The distance a wave travels in a certain amount of time
Which medium does waves move fastest through
solid
Reflection
When life bounces off a surface or an object at equal angles
Longitudinal wave
Vibration that move back and forth in the same direction the wave is traveling
True or False: Sound can travel without a medium
False
Amplitude
The distance a wave moves back and forth from its resting position
What medium does waves move medium speed through?
Liquid
What property of light and sound wave would it be if water bends when hitting water?
Refraction
Which wave moves perpendicular from the energy source?
Transverse
Light
At transverse wave that travels perpendicular to the motion of the particles
Frequency
Number of back and forth movements produced in a certain amount of time
What medium do waves move the slowest through?
Gas
DAILY DOUBLE
Absorbtion
When atoms in matter take in light energy and then convert it to another form, like heat energy.
DAILY DOUBLE
Transverse Wave
Have vibrations of particles that move back and forth at right angle to the direction the wave is traveling
Sound
A longitudinal wave that travels parallel to the motion of the particles
