Finals Test Flashcards
Interference
The meeting and combining of waves
X Rays
an electromagnetic wave of high energy and very short wavelength
Longitudinal Wave
a type of wave in which the disturbance move the same direction that the wave travels.
Transverse Wave
a wave in which the disturbance moves at right angles to the direction of the wave.
Mechanical Wave
A wave such as a sound or seismic wave that transfers kinetic energy through matter.
Wave
A disturbance that transfers energy from one place to another with out requiring matter to move the entire distance.
Transmission
the action or process of transmitting something
Radio Waves
an electromagnetic wave of a frequency
Electromagnetic Spectrum
Energy that travels across distances.
Trough
the lowest point or valley of a wave.
Wavelength
the distance from one crest to the next wave crest.
Reflection
the bouncing back of a wave after it hits a barrier.
Medium
A substance through which a wave moves.
Crest
The highest point or peak of a wave.
Amplitude
the maximum distance that a disturbance causes a medium to move.
Frequency
the number of waves that pass a fixed point in a given period of time.
Refraction
the bending of light as it crosses a boundary between two mediums
Diffraction
the spreading out of waves as they pass through an opening or around the edges of an obstacle.
Radiation
the emission of energy as electromagnetic waves
Electromagnetic Wave
one of the waves that are propagated by simultaneous variations of electric and magnetic field intensity
Microwaves
an electromagnetic wave with a wavelength in a certain range.
Infrared Light
Has a wavelength just greater than that of the red end of the visible light spectrum
Ultraviolet Light
a wavelength shorter than that of the violet end of the visible spectrum.
Gamma Rays
penetrating electromagnetic radiation
