CEM 141 Test Latest Updated Questions with 100%
Complete Solutions
Wavelength (λ)
The top of one peak to another, distance in m or nm
Amplitude
the height of peaks (intensity)
Frequency (v)
the number of waves per second, Hz, 1/s, or s^1
Frequency vs Wavelength
Energy of light increases as frequency increases and wavelength decreases
Inverse relationship waves and frequency
Bigger wavelength, smaller frequency
Inverse symbols
v & λ are inverse
Speed of Light Equation
C=λ*v
Order of Electromagnetic Spectrum
1 Gamma rays
2 X-rays
, 3 Ultra Violet
4 Visible Light
5 Infrared Rays
6 Microwaves
7 Radio waves
Wavelengths
λ
Frequency
v
Speed of light
3x10^8 m/s
Planck's Constant
6.626x10^-34
Saying for Longest waves to shortest waves
Raging Martians Invaded Venus Using X-Ray Guns
in phase/constructive interference
Amplitude doubles, Crest and Trough reinforced
Out-of-Phase/Deconstructive interference
Crest and trough cancel each other out
