INTRODUCTION
In this PhysicsQuest you will learn about
phenomena and applications of
the Physics of Light.
PROCESS AND RESOURCES
- Visit the links provided for each section and neatly
type the answers to the questions.
- Please use your own words!
SECTION 1. THE ELECTROMAGNETIC SPECTRUM
The "electromagnetic spectrum" is a term used to describe the
entire range of light radiation, from gamma rays to radio waves.
We tend to think of optical radiation as "light," but the rainbow
of colors that make up optical or "visible" light is just a tiny part
of a much broader range of light energy.
1. Make a table with three columns that include the following information:
- the names of the seven types of radiation that make up the
Electromagnetic Spectrum
- Main characteristics of each type of radiation
- Data of the wavelength and frequency of each type of radiation
2. Describe how each of the seven types of radiation is used in our everyday lives or in certain industries.
Suggested Links:
Electromagnetic radiation is used widely in Space Exploration.
3. Write down at least two of the space items that can be observed by:
x-rays, ultraviolet, visible, infrared and radio waves.

SECTION 2. VISIBLE LIGHT
Normally when we use the term "light," we are referring to a type of
electromagnetic wave that stimulates the retina of our eyes.
In this sense, we are referring to visible light, a small spectrum of the range of frequencies of electromagnetic radiation. This visible light
region consists of a spectrum of wavelengths, which range from 700 nanometers (abbreviated nm) to approximately 400 nm.
This narrow band of visible light is affectionately known as ROYGBIV.
4. What does each letter stand for?
5. Explain how How Roy G. Bv lost a vowel.
Link:
Each individual wavelength within the spectrum of visible light wavelengths is representative of a particular color.
6. Write down the wavelength for each color.
