Electromagnetic Spectrum
Learning Objectives
- Students will be able to identify regions of the electromagnetic spectrum
- Students will be able to describe the properties and applications of each region
- Students will be able to relate wavelength/frequency to energy and properties
Core Concepts
- radio_waves
- microwaves
- infrared
- visible_light
- ultraviolet
- x_rays
- gamma_rays
- wavelength_spectrum
- frequency_spectrum
Formulas
$$E = hf = \frac{hc}{\lambda}$$
Energy of electromagnetic radiation
$$f \lambda = c$$
Relationship between frequency, wavelength, and speed of light
Units
| wavelength | λ (nanometers to kilometers depending on type) |
| frequency | f (Hz) |
Interesting Fact
Humans can only see a tiny portion (visible light) of the electromagnetic spectrum
Key Scientist
James Clerk Maxwell
Predicted the existence of electromagnetic waves
Ancient Wisdom
The invisible spectrum parallels spiritual teachings that reality transcends sensory perception; meditation and spiritual practice access hidden dimensions.
