3. Electromagnetic radiation are energy waves created by electromagnetic sources. An example of electromagnetic radiation: Radio waves.
4.a) In order (ascending): Ultraviolet, X-Ray, and Gamma Rays.
b) UV rays: Kills Bacteria, cleans water, and used for forensic purposes.
X-Ray: Medical Imaging.
Gamma Rays: Medical Imaging.
5.a) In order (ascending): Radio waves, Microwaves, Infrared waves.
b) Radio Waves: Communication.
Microwaves: Culinary purposes, Cooking.
Infrared Waves: Detect energy loss.
6. The higher the frequency, the shorter wavelength, and the higher power the electromagnetic radiation would have.
The lower the frequency, the longer wavelength, and the smaller power the electromagnetic radiation would have.
7. Violet, Blue, Green, Yellow, Orange, Red.
8.a) Red light has a longer wavelength.
b) Blue would have a higher frequency due to shorter wavelength.
9.They will see yellow when red light and green light overlap.
10.a) They both are types of electromagnetic radiation.
b) They both have different frequencies and wavelengths.
11.a) Very short wavelength.
b) Shorter wavelengths= higher frequency= deadlier radiation and higher radiation levels
higher radiation exposed to body can cause DNA mutations within cells and cancer.
12.a) Its probably going to appear black since no light is bouncing off the balloon (theoretically).
b) Its probably going to appear black since there is no light bouncing off the balloon.\
13. Since an object "bounces off" the colour of rays that are equivalent to its colour. In this case if you paint a house white, it would bounce off all the light rays since white light is made out of every colour within the spectrum. Therefore the building would not absorb any light energy to convert to heat which will keep it cool within the building
