Wavelength is the distance from one crest of a wave to another, whereas frequency is the number of waves within a second.
The electromagnetic spectrum consists of varying forms of energy within oscillating electric and magnetic fields.
Concept: The Electromagnetic Spectrum3m
Concept: Wavelength & Frequency2m
Concept: The relationship between Wavelength & Frequency4m
Wavelength and Frequency are inversely proportionally, meaning that if one increases then the other one must be decrease.
Problem: A. Based on the images of different electromagnetic waves, answer each of the following questions.4m
Concept: Converting between Wavelength & Frequency1m
To convert between wavelength & frequency we use the equation c = ν λ, where c equals the speed of light.
Example: Even the music we listen to deals with how energy travels to get to our car radio. If Power 96 broadcasts its music at 96.5 MHz (megahertz, or 106 Hertz) find the wavelength in μm and Å of the radio waves.4m
Problem: PRACTICE: Calculate the frequency of the red light emitted by a neon sign with a wavelength of 663.8 nm.3m
