Waves Color
If a shirt reflects all colors, what color is the shirt?
White
mechanical waves cannot carry energy through this
A vacuum/space
The highest point of a tranverse wave
Crest
A material that lets some but not all light through
translucent
The type of lens that combines light beams
convex lens
What color absorbs all light?
Black
Electromagnetic spectrum
The lowest point of a transverse wave
What is the trough?
matter takes in light's energy
absorption
Type of lens that spreads out light beams
concave lens
What visible color is has the longest wavelength?
Red
Every wave, regardless of type or medium, transfers this
What is energy?
The measurement of a wave from the resting line to the crest.
Amplitude
when a wave strikes a surface and bounces off is called
What is reflection?
A mirror that makes light waves come together, making the image become bigger
Concave mirror
What visible color has the shortest wavelength?
Purple/Violet
This type of wave vibrates matter in the opposite direction from how the wave is moving.
What is a transverse wave?
The number of wavelengths that pass a given point per second.
What is frequency?
light passes through a medium without much change
transmission
A mirror that spreads light waves apart, making the view bigger
Convex mirror
What are two colors we cannot see?
Infrared and ultraviolet
EM waves are an example of this type of wave
What is a transverse wave?
The distance from peak to peak
What is wavelength?
how a wave changes speed as it moves from one medium into another
Refraction
The angle of incidence (incoming light ray) is equal to the angle of reflection
Law of Reflection
