This is practice understanding electromagnetic waves.
Organize the waves of the electromagnetic spectrum from the lowest frequency to the highest frequency.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
microwave | arrow_right_alt | 1 lowest frequency |
visible light | arrow_right_alt | 2 |
radio | arrow_right_alt | 3 |
ultraviolet | arrow_right_alt | 4 |
gamma | arrow_right_alt | 5 |
infrared | arrow_right_alt | 6 |
x-ray | arrow_right_alt | 7 highest frequency |

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
