Question

Give two uses of Microwaves.

Explain the uses of microwaves.

Answer 1

1. In radar system for aircraft navigation
2. Microwave oven for cooking

Answer 2

1. Radar Systems: Due to their short wavelengths, they can be beamed in a specific direction to detect aircraft and for navigation.
2. Microwave Ovens: They are used for domestic cooking because their frequency matches the resonant frequency of water molecules, causing them to vibrate and heat the food.
3. Satellite Communication: Due to their high frequency, they can easily penetrate the Earth's ionosphere to transmit signals to satellites without getting reflected back.
4. Weather Forecasting: They are used in specialized Doppler radars to track clouds, measure wind speeds, and predict rainfall or severe weather conditions.
