# Electromagnetic Waves

## What kind of disturbance creates an electromagnetic wave?

Electromagnetic waves are created by interferance.

## What are two ways that EM waves are different from mechanical waves?

-Electromagnetic waves are able to pass through a vacuum unlike a Mechanical wave which require a medium to transport energy through.

-Mechanical waves are created by a disturbance or vibration in matter, Electromagnetic waves are created by a vibrating electric charge.

The wavelenght of Radio is greater than 1 x 10^-1. The frequencey is less than 3 x 10^9. The energy is less than 2 x 10^-24. Two examples are AM radio and Amateur radio.

## Microwave

The wavelenght of Microwave is 1 x 10^-4. The frequencey is 3 x 10^-2. The energy is 2 x 10^-46. Two examples are Microwave and microwave oven.

## Infared

The wavelenght of Infared is 6 x 10^-10. The frequencey is -1 x 10^-3. The energy is -1 x 10^-41. Two examples are TV romote control and night vision goggles.
