Parts
The highest point in a wave
crest
The pitch of a sound depends on the sound waves...
frequency
The visible spectrum of light is broken up into what colors
ROYGBIV
When wavelength decreases, frequency _______
increases
a wave in which the vibrations travel perpendicular to the direction of the wave is called
transverse wave
The lowest point in a wave
trough
The loudness of a sound depends on the waves...
amplitude
When light interacts with matter and "bounces off" this is called
Reflection
If you increase the frequency of a sound wave what is the result?
higher pitch
a wave that the vibrations travel in the same direction as the wave is called
longitudinal
Amplitude is measured by...
The distance between the point of origin and the crest or trough
Frequency of sound waves is measured in...
Hertz (Hz)
When light interacts with matter and is taken in, often raising the temperature of the object this is called
Absorption
If you decrease the amplitude of a sound wave what is the result
lower, or softer sound (less loud)
What is the color of visible light with the lowest frequency?
red
The distance between two troughs of a transverse wave is equal to its...
wavelength
When sound waves reflect off of matter this is called...
an echo
Describe what is happening when we look at an object and see red
What are two ways you can measure wavelength?
1. crest to crest
2. trough to trough
3. one full cycle (up to crest, pass through point of origin, down to trough, back to point of origin)
When light passes through matter it is called
transmission
compressions
Sound is what type of wave?
longitudinal
Light waves are a narrow band on the _______________ spectrum
Electromagnetic
A wave diagram that is 15m long shows 3 crests and 3 troughs. What is the wavelength of this wave?
5m
When we see a rainbow, we are seeing white light being bent by water in the atmosphere. What is this called (the bending part)?
refraction
