Transparent
a material that allows almost all of the light striking it to pass through, and through which objects can be seen clearly
a material that allows most of the light striking it to pass through, and through which objects can be seen blurry
Translucent
a material that allows almost all of the light striking it to pass through, and through which objects can be seen clearly
material that allows most of the light that strikes it to pass through, but through which objects appear blurry
Opaque
a material through which light does not pass
a material that lets all the light to pass through it
Compresssion
a region of a longitudinal wave where the particles of the medium are closest together
the region of a longitudinal wave where the particles are farthest apart
Wave
Begin with a source of energy that causes a back and forth or up and down disturbance, or movement
Does not transfer matter
Intensity
amount of energy that passes through a square meter of space
a material through which light does not pass
Mechanical Wave
a wave that can travel through empty space or through matter
a wave that travels only through matter
Electromagnetic Wave
a wave that travels only through matter
-a wave that can travel through empty space or through matter
Transverse
a wave that moves up and down or side to side
a wave that moves up and down or side to side
Longitudinal
a wave that moves up and down or side to side
a wave that moves backwards and forwards
Pitch
-the perception of how high or low a sound seems
the unit used to measure sound intensity
Rarefaction
- the region of a longitudinal wave where the particles are farthest apart
-a region of a longitudinal wave where the particles of the medium are closest together
Refraction
the change in direction of a wave as it changes speed, moving from one medium
The change in direction of a wave when it travels past the edge of an object or through an opening
Reflection
Bounces back
Absorbs the light
Radio Waves
low frequency, low energy EM wave that has a wavelength longer than 30 cm
Used to cook food, carry cell phone signals
Ifrared Waves
-EM wave with a wavelength shorter than a microwave but longer than light
-EM wave with a slightly shorter wavelength and higher frequency than light
Ultraviolet Waves
-EM wave with a slightly shorter wavelength and higher frequency than light
-EM wave with a wavelength shorter than a microwave but longer than light
Microwaves
-EM wave with a wavelength shorter than a microwave but longer than light
Used to cook food, carry cell phone signals
X-rays
High energy EM waves that have slightly shorter wavelengths and higher frequencies than UV rays
a material that allows almost all of the light striking it to pass through, and through which objects can be seen clearly
Gamma Rays
EM waves produced by vibrations within the nucleus of an atom
-EM wave with a slightly shorter wavelength and higher frequency than light
Transmission
Carry energy
Carry matter
Diffraction
The change in direction of a wave when it travels past the edge of an object or through an opening
EM waves
Absorption
Energy increases the motion of particles and changes to thermal energy
Bounces back
Decibel
Hertz
the unit used to measure sound intensity, or loudness
