Chapter 4 Many properties of light can be understood using a wave model of light.

In this section, we can learn about using microwaves in many different ways. Such as microwaves can be use to transmitted to telecommunications sateilles that orbit Earth. Shorter wavelength microwave is used in remote sensing, which is just like a radar. In other words, typical microwaves are like radars. Also, in this section, we can learn about what kind of food can be microwaved, and what kind of food can't be microwaved.
