An explanation of what exactly is electromagnetic radiation:
* Note that this video talks about how light is both a particle and a wave. At the moment we're just going to be talking about light as a wave, but it's good to be aware of the duality. If you're interested in the wave-particle duality a highly recommend looking more into it yourself.
Introduction to EM waves, their uses in everyday life and what makes each type of wave different from each other:
*If you get the time, watch the other videos in this series that go into each type of EM radiation in more depth.
A fun summary of the EM spectrum in song form:
Use this interactive to see how the wavelength, frequency and energy levels change as you move through the EM spectrum. Make sure to read the different uses for each type of radiation:
Play with this interactive an what you would see if you could see other parts of the EM spectrum:
Match the candidate
Read the following bios and match it to one of the types of EM radiation:
a. I'm a very low energy, easy going type of person. I believe in the power of communication, and want to link people of long distances with many different types of communication.
b. I'm like to study people, and often I can see right through them. I also like looking at faraway stars, especially when they have big supernova explosions.
c. I'm a fun person, usually hanging out in the outdoors getting a tan. I make sure everyone is happy and healthy by giving out Vitamin D, but if I'm around too much I can get nasty and start hurting people with burns and if I'm around too much I can get really nasty and give people cancer.
d. I'm a very warm person, and I spread my warmth to everyone around me. I often like to sit on the sofa changing channels. I'm also very good at seeing at night time.
e. I love cooking, and you'll often see me warming up water molecules to make food. I also pride myself on being able to send people a lot of information in a fast amount of time.
f. I have too much energy for people to handle. I hurt people almost as soon as I see them, so usually you'll just see me hanging around colliding neutron stars and solar flares.
g. I love to wear really colourful, rainbow colours. I'm out and about everyday where people can always see me. I also love to garden, and everyday I'm feeding all the plants.
Who's the winning candidate?
Now that you have studied each type of EM radiation, it's time decide which is the most important to humans. Write a 150-200 paragraph on what you think is the most important type of EM radiation to humans. Explain why you think that and back up your example with specific examples.
Write your answer on your device and submit them through the 'EM radiation webquest' link on the Learning Management System.
