PLEASE HELP ME I WILL PAYPAL YOU $5 dollars but please help me 5. How does the wavelength of waves used in microwave
ovens compare with the wavelength of waves used for
radar?

6. Which color of visible light has the longest wavelength?
The shortest?

5) The wavelength of microwaves are much shorter compared to radio waves (sonar). Microwaves also have a shorter frequency.

6) Red has the longest wavelength (think infrared), and purple/violet has the shortest wavelength (think ultraviolet).

REFERENCE:

In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.
