characteristics of waves
the height of a wave
what is the amplitude
Electromagnetic waves with the shortest wavelengths and highest frequencies
what are gamma rays
A wave in which the vibration of the medium is parallel to the direction the wave travels
what are longitudinal waves
λ=v/f.
what is the wavelength equation
can occur when light moves along a path from a medium with a higher index of refraction to one with a lower index of refraction.
what is total internal reflection
the number of complete wavelengths that pass a point in a given time
what is the frequency
type of electromagnetic (EM) radiation with wavelengths in the electromagnetic spectrum longer than infrared light.
what are radio waves
A wave in which the particles of the medium move perpendicularly to the direction the wave is traveling
what are transverse wave
n1sinθ1 = n2sinθ2
what is snells law equation
the process of seperating polychromatic light into its component wavelengths
what is dispersion
The distance between two corresponding parts of a wave
what is the wavelength
a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter; with frequencies between 300 MHz and 300 GHz.
what are microwaves
also known as stationary wave, is a combination of 2 waves moving in the opposite directions, each having the same amplitudes and frequency
what are surface waves
hookes law equation
what is F = -kx
a light source that has a single wavelength
what is monochromatic
the time taken for one complete cycle of vibration to pass a given point.
what is the period
a form of electromagnetic radiation, similar to light but of shorter wavelength and capable of penetrating solids and of ionizing gases.
what are x-rays
highest point in wave
what is the wave crest
path difference between 2 wavelengths=an integer multiple of the wavelength.
what is constructive interference
a device that produces coherent light at a single wavelength
what is a laser
frequency x wavelength = ?
what is the wave speed
a type of radiant energy that's invisible to human eyes but that we can feel as heat.
what are infrared rays
lowest point in wave
trough
speed of light in a vacuum/speed of light in medium
what is index of refraction
the focusing of different colors of light at different distances behind a lens
what are chromatic aberrations
