|
The transfer of energy carried by light waves to particles of matter.
|
Absorption
|
|
|
|
The maximum distance a wave vibrates from its rest position.
|
Amplitude
|
1/2 the height of a wave.
|
|
|
The number of waves produced in a given amount of time.
|
Frequency
|
The higher number of waves the higher the energy.
|
|
|
The bouncing back of a wave after it strikes a barrier or an object.
|
Reflection
|
Ex. looking at yourself in the mirror
|
|
|
The bending of a wave as it passes at an angle from one medium to another.
|
Refraction
|
Ex. pencil in a glass of water and it appears broken.
|
|
|
A disturbance that transmits energy through matter or space.
|
Wave
|
|
|
|
The distance between one point on a wave and the corresponding point on an adjacent wave in a series of waves.
|
Wavelength
|
|
|
|
Material in which a wave passes through
|
Medium
|
solid, liquid, or gas
|
|
|
The passing of a wave through a medium.
|
Transmission
|
|
|
|
The release of light energy by particles of matter that have absorbed energy.
|
Scattering
|
When light does this, it does it in all directions.
|
|
|
The emission of energy in the form of EM waves.
|
Radiation
|
|
|
|
A wave in which the particles of the medium vibrate back and forth along the path in which the wave travels.
|
Longitudinal Wave
|
Sound waves
|
|
|
A wave in which the particles of the medium vibrate perpendicular to the wave traveling
|
Transverse Wave
|
Light waves
|
|
|
Light produced by hot objects.
|
Incadescent Light
|
Home Lights
|
|
|
Visible light emitted by a phosphor particle when it absorbs energy such as ultraviolet light.
|
Fluorescent Light
|
School Lights
|
|
|
The entire range of electromagnetic waves.
|
Electromagnetic Spectrum
|
|
|
|
The apparent change in the frequency of sound caused by either the listener or the source of the sound
|
Doppler Effect
|
|
|
|
The process of using reflected sound waves to find objects. Bats use this in order to navigate around borders and find insects to eat.
|
Echolocation.
|
|
|
|
A waves that can travel through space or matter and consists of changing electric and magnetic waves.
|
Electromagnetic waves
|
|
|
|
Term describing sounds with frequencies lower than 20 Hz.
|
Infrasonic
|
|
|
|
Term describing sounds with frequencies higher than 20,000 Hz.
|
Ultrasonic
|
|
|
|
States that the angle of incidence is equal to the angle of reflection. Incidence in the falling of a beam of light on a surface.
|
Law of reflection
|
|
|
|
Material in which light is not transmitted (does not pass through)
|
Opaque
|
|
|
|
Material in which light is transmitted but is scattered.
|
Translucent
|
|
|
|
Material in which light is transmitted easily.
|
Transparent
|
|
|
|
The release of light energy by particles of matter that have absorbed energy.
|
Scattering
|
|
|
|
The very narrow range of wavelengths and frequencies in the electromagnetic spectrum that humans can see.
|
Visible light
|
|
|
|
A types of electromagnetic wave that is produced by the sun and sometimes has negative effects such as sunburn, skin cancer, wrinkles and eye damage.
|
Ultraviolet Light
|
|
|
|
What are the Primary colors of light?
|
Red, green, and blue
|
|
|
|
What does ROY G. BIV stand for?
|
the colors of the visible spectrum red, orange, yellow, green, blue, indigo, and violet.
