Electromagnetic Radiation
|
This includes different types of light such as visible light, x-rays, microwaves, gamma waves, radio waves, etc
|
Energy in light behaves like waves. This version of classification led us to understand that light can behave like a wave.
|
|
|
Wave Nature of Light
|
Decided by the variables of frequency and wavelength
|
Frequency and Wavelength are closely related and depend on each other
|
|
|
Frequency
|
The number of cycles the wave undergoes per second
|
v (nu); expressed in hertz
|
|
|
Wavelength
|
The distance between any point on a wave and the corresponding point on the next crest/trough of the wave; the distance the wave travels during once cycle,
|
expressed in meters or angstroms (10^-10 meters)
|
|
|
Speed of Light
|
A constant equivalent to 3.00 x 10^8 m/s in a vacuum
|
expressed as c
|
|
|
Speed of a Wave
|
The distance traveled per the unit of time - describes the velocity
|
c = wavelength x frequency
|
|
|
Amplitude
|
A height of a crest or a depth of a trough - was THOUGHT to be a measure of the intensity of light, which we perceived as brightness
|
A = amplitude
|
|
|
Electromagnetic Spectrum
|
Continual radiant energy; different parts utilized for specific uses
|
All waves in the spectrum travel at the same speed through a vacuum, but differ in wavelength and frequency
|
|
|
Monochromatic Light
|
Light of a single wavelength/frequency
|
One single color
|
|
|
Polychromatic Light
|
Light of multiple wavelengths/frequencies
|
White light; most of the light we see is this
