Wave Vocab Flashcards
Wave
A disturbance that transfers energy from one place to another with out requiring matter to move the entire distance
Medium
A substance in which a wave moves
A mechanical wave
a wave such as a sound on seismic wave that transfers kinetic energy through matter
Transverse wave
A wave in which the disturbance moves at right angles to the direction of the wave
Longitudinal wave
A type of wave in which the disturbance moves in the same direction that the wave travels.
Crest
the highest point or peak of a wave
Trough
the lowest point or valley of a wave
Amplitude
the maximum distance that a disturbance causes a medium to move from its resting postition
Wave length
the distance from one crest to the next wave crest
Frequency
The number of waves that pass through a fixed point in a given period of time
Reflection
the throwing back of a wave after it hits its barrier
Refraction
the bending of light as it crosses boundary between two mediums at an angle other than 90 degrees
Diffraction
the spreading out of waves as they pass through an opening or around the edges of an obstacle
Interference
The meeting and combining of waves: the adding or subtracting of a wave amplitudes that occur as waves overlap
Electromagnetic waves
A type of wave such as light waves or radio waves that do not require a medium to travel through a disturbance that transfers energy through a field
Radiation
Energy that travels across distances in the form of electromagnetic waves
Electromagnetic spectrum
A range of all electromagnetic frequencies
Radio wave
The part of the electromagnetic spectrum that consists of waves of the lowest frequencies
Microwave
Part of the electromagnetic spectrum that consists of waves with a higher frequency than radio waves but lower frequencies than infrared waves
Infrared light
Part of the electromagnetic spectrum that consists of waves with frequencies between those of microwaves and visible light
Ultraviolet light
The part of the electromagnetic spectrum that consists of wave frequencies higher than those of visible light and lower than
x-rays
X-ray
The part of the electromagnetic spectrum consists of waves with high frequencies and high energies electromagnetic wave with frequencies ranging from 10 to the 16th to 10 to the 21 power of hertz e
Gamma ray
The part of the electromagnetic spectrum that consists of waves with high frequencies
Transmission of light
The passage of waves through a medium
