When you set the mousetrap, you are using a second-class lever. Sorry if I get this wrong. I am in 5th grade! ♥
We use a spectrometer to help us determine what stars and planets are made of by passing a light through various chemical elements, different spectral patterns are created. By matching those patterns up to patterns generated in a laboratory environment we can tell what the composition of a distant star or planet is.
I am pretty sure that infrared waves are part of the electromagnet spectrum produces heat and with special equipment can locate people at night. I choose this options because <span>gamma rays can be harmful to people, and other options just make no sense.</span>
