Match the kind of electromagnetic radiation to the likely use in technology.

Radiant energy spreads out rom its source in all directions

Electromagnetic radiation includes only visible light waves.

Microwaves are a type of infrared wave.

X-rays have more energy than gamma rays

Radio waves, microwaves and infrared waves all have longer wavelengths than visible light.

Both x-rays and gamma rays have higher frequencies than ultraviolet rays

The sun radiates both visible light and invisible energy.

Communicating with satellites is an application of gamma rays
