3.1 and 3.2 vocab Flashcards
Wave
A disturbance that transfers energy from one place to another without transferring matter
Energy
The ability to cause change
Medium
A material in which a wave travels
Transverse Wave
A wave in which the disturbance is perpendicular to the direction the wave travels
Crest
The high point of a transverse wave
Trough
The lowest point on a transverse wave
Amplitude
The maximum distance that the wave moves from its rest position
Wavelength
The distance between one point on a wave and the nearest point just like it
Frequency
The number of time the pattern repeats in a given amount of time
Electromagnetic Wave
A typeof wave created by vibrating particles
Electromagnetic Spectrum
The range of all types of electromagnetic radiation
Infrared Wave
An electromagnetic wave that has a wavelength shorter than a microwave but longer than light
Visible Light
Electromagnetic waves that your eyes can see
X-Ray
A high-energy electromagnetic wave that has a slightly short wavelength and higher frequency than an ultraviolet wave
Ultraviolet Wave
An electromagnetic wave that has a slightly shorter wavelength and high frequency than light and carries enough energy to cause chemical reactions
Sterilization
Process of elimination any form of microorganisms
Gamma Ray
A high-energy electromagnetic wave with a shorter wavelength and a higher frequency than all other types of electromagnetic waves
Fiber Optics
The process of transmission of information using light pulses along optical fiber
Microwave
A low-frequency, low energy electromagnetic wave that has a wavelength between about 1mm and 30cm
Radio Wave
