Electromagnetic Wave Flashcards
Highest point in wave
Crest
Lowest point in wave
Trough
Distance from midpoint to highest or lowest in wave
Amplitude
Distance between two successive identical parts of wave
Wavelength
Refers to disturbance of waves produced in one second
Frequency
Result from vibrations between electric and magnetic fileds
Electromagnetic wave/radiation
Empty of matter free space
Vacuum
Limits which variation is possible
Range
Medium move -> direction wave moves
Transverse wave
Do not require a medium to propagate
Em waves
Range of different em waves
Electromagnetic spectrum
Radio,microwave,infrared,
visible,ultraviolet,x ray,gamma ray
Surface wave propagation
Below 3mhz
Ground wave propagation
Ionosphere wave propagation
Skywave propagation
Tropospheric wave propagation
Space wave propagation
Radiation emitted by electromagnetic wave
Energy
Exact multiplier
Planck’s constant
6.63x10^-34 j.s
Number of cycles wave passes in a second
Frequency
3x10^8 m/s or c
Speed of light
C = (lambda)f
C-> speed of light
F-> frequency
Lambda -> Wavelength
E= (h)f
E-> energy
H-> Planck’s constant
F-> frequency
E=h c/lambda
Energy = Planck’s constant x speed of light divided by the wavelength
Formula for lambda
Lambda = constant speed of light divided by frequency
Formulas for frequency
Frequency= speed of light divided by lambda
F= energy divided by Planck’s constant
