1
Q
Electromagnetic Spectrum
A
Visible light Radio waves Microwave radiation Infrared Ultraviolet Gamma rays X-rays
2
Q
Properties of Waves
A
Characterized by wavelength, frequency, and amplitude
3
Q
Wavelength
A
Distance between identical points on successive waves
4
Q
Frequency
A
Number of waves that pass a certain point in one second
5
Q
Amplitude
A
Vertical distances from the midline of the wave to the top of the peak or the bottom of the triangle
6
Q
Speed of light through a vacuum
A
299792458 m/s
7
Q
Speed of light equation with frequency and wavelength
A
C = (wavelength)(frequency)
Units of wavelength = meters
Units of frequency = reciprocal second
8
Q
Maxwell’s theory
A
Electromagnetic wave has an electric field and magnetic field component that travel in perpendicular planes
9
Q
What happens to wavelength when frequency goes down?
A
As frequency goes down, wavelength goes up.
