Waves and Electromagnetic Spectrum Only
Terms in this set (...)
a complete back-and-forth motion of an object.
energy waves bouncing off the surface of an object (mirrors or echoes return energy back to their source)
a longitudinal wave consisting of compressions and rarefactions, which travels through a medium
the bouncing of light off an object
the bending of light as it moves through mediums
medium allows some light to pass through
medium allows light to pass through
medium does not allow light to pass through
seven colors of light; ROYGBIV
angle of incidence
an angle between the incoming light ray and the normal.
angle of reflection
the angle between the normal and the ray of light leaving the mirror.
a ray of light going towards the mirror or another object.
all the colors are reflected to form this
a ray of light bouncing off a mirror.
a block of clear, colorless glass/plastic. Usually triangular.
Name two types of mechanical waves.
transverse and longitudinal
Which type of wave contains compressions and rarefactions?
What is a Wave?
a disturbance that travels from one place to another transporting energy
a type of material through
which a wave travels (solids, liquids or gasses)
What are 3 types of media a mechanical wave can travel through?
gases, solids, & liquids
cycles per second. How many waves can pass a given point per second
In order from fast to slow name the mediums through which waves travel through
solids, liquids and gases
the speed at which a wave travels through a medium. (frequency x wavelength)
the interaction of two or more waves that combine in a region of overlap
the interaction among two or more waves in which combine to produce a larger wave
the interaction among two or more waves in which combine to produce a wave with a smaller wave
the bending of waves around corners or barriers
waves that require a medium through which to travel
Which type of wave moves in an up and down motion?
What type of wave moves parallel to the wave energy?
Which type of wave does not require a medium?
maximum distance a wave varies from its rest position, or the normal line.
the distance from two corresponding (or the same) parts of a wave.
highest point of a wave
lowest point of a wave.
the part of a longitudinal wave where the particles of the medium are close together.
the part of a longitudinal wave where the particles of the medium are farther apart.
On the Electromagnetic Spectrum, if a wave has low frequency it must also have
Which has a higher frequency, red or yellow waves?
Which has a higher frequency, green or blue waves?
Which has a larger wavelength, red or yellow waves?
Which has a larger wavelength, green or blue waves?
Which has more energy, X-rays or microwaves?
Which has more energy, ultraviolet or visible light waves?
Which has a smaller wavelength, infrared or visible light waves?
Which has a smaller wavelength, visible light or ultraviolet waves?
Example of a use for microwaves
Cell phone signals
Example of a use for x-rays
take internal pictures of the human body
Example of a use for ultraviolet rays
Example of a use for infrared
heats the Earth
Example of a use for RADAR (type of radio wave)
police use them in speed traps
Example of a use for visible light
what the human eye can see
Frequency of ALL waves is measured in what unit?
