The study of the interaction between matter and electromagnetic radiation
Define Electromagnetic Radiation
Electromagnetic Radiation is a form of energy that includes visible light, heat and other radiations like x-rays and gamma rays.
Long wavelength + Low frequency =
Short wavelength + High frequency =
Give an example of low energy waves
Give an example of high energy waves
Wavelength measures the?
distance between adjacent waves
What is the symbol for wavelength?
Velocity of radiation or Speed is a constant, what is the symbol used?
What are the units of measurements for λ?
What are the units of measurement for c?
Frequency measures what?
The number of wavelengths passing a fixed point per sec
Give the symbol for frequency
What is the symbol for wavenumber?
What are the units of measurements for frequency?
s-1 or Hz
What are the units of measurement for wavenumber?
What is the equation used to relate veloctiy, wavelength and frequency?
What is the equation triangle that relates c,f,λ?
To convert into meters for wavelength: 1nm =
Conversion of wavelength into energy can be accomplished by using the equaiton:
Therefore to calculate energy, the combined equation that can be used is:
E = Lhc/λ
