Answer the following question given this paragraph: Find the microwave in the Figure above . A microwave is an electromagnetic wave with a relatively long wavelength and low frequency. Microwaves are often classified as radio waves, but they have higher frequencies than other radio waves. With higher frequencies, they also have more energy. That's why microwaves are useful for heating food in microwave ovens. Microwaves have other important uses as well, including cell phone transmissions and radar. These uses are described below. You can learn more about microwaves and their uses in the video at this URL: http://www. youtube. com/watch?v=YgQQb1BVnu8 . Q: Why do microwaves have a higher energy than radio waves? A:
OPTIONS:
- higher resonance
- lower frequency
- higher decibel
- higher frequency

Answer:
higher frequency
