What are 3 ways that electromagnetic radiation is used to improve your everyday lives?

The first type of a electromagnetic wave is an x - ray it helps us today because it helps us see our bones. The second one is a microwave the microwave it helps us warm our food. The last one is light it helps us see in the dark.

==============================

-- Visible light was useful to me today when it enabled me to see things, and avoid

bumping into them as I drove my car to the grocery store.

-- Infrared radiation from the sun was useful to me because it allowed me to make

the trip to the store without a heavy jacket.

-- Microwave radiation was directly useful to me when I re-heated my coffee in the

radar oven, but it was vastly more useful to me in an indirect way. Microwave radiation,

by its very existence, makes it possible for me to earn a living as a microwave engineer.
