Research an Electromagnetic Spectrum region
Learning goals:
- Students will be able to define the electromagnetic spectrum
- Students will be able to describe the frequency, and wavelength of the
different regions of the EM spectrum
Electromagnetic (EM) radiation is a form of energy that is all around us and takes
many forms. The EM spectrum contains a broad range of electromagnetic
wavelengths.
The Electromagnetic Spectrum spans an enormous range of wavelength and
frequencies. The EM spectrum is generally divided into seven regions, in order of
decreasing wavelength and increasing energy and frequency.
The common designations are: radio waves, microwaves, infrared (IR), visible light,
ultraviolet (UV), X-rays and gamma rays
Research your assigned EM spectrum region and answer the following
questions:
1. What is frequency and what is the frequency range of the specific EM
spectrum region?
2. What is wavelength and what is the wavelength range of the specific EM
spectrum region?
3. Where along the EM spectrum does this region sit?
4. List at least three uses/functions for this EM spectrum region
5. At least one interesting fact about this EM spectrum region
6. Who and when discovered the specific EM spectrum region?
Present your findings in a group with other students in a breakout room on zoom the
following lesson. Use the following table to fill in the information taught by the other
group members
