Science: Class Response

Three Facts :

1.) Electromagnetic Spectrum is the complete range of electromagnetic waves placed in order of increasing frequency.

2.) Radio waves are the electromagnetic waves with longer wavelengths and lowest frequencies.

3.)Infrared Rays are electromagnetic waves with wavelengths shorter than those of radio waves.

4.) Visible light is electromagnetic waves you can see.


My opinion on this is that it's fun to learn about the electromagnetic spectrum. I didn't remember a lot about the spectrum, and it was a nice brush up on it. I also learned that an example of infrared rays is a heat lamp because it gives off infrared rays. An example of a radio wave is not only a radio is when a broadcast station sends out radio waves, and we can hear it on our radio or television. Below are websites about this topic:
