Question

which ems wave has a wavelength equal to the size of a fly and is used for heating food and transmitting information? infrared radio waves microwaves visible

Explanation:

Microwaves have wavelengths ranging from about 1 millimeter to 1 meter. A fly is typically a few millimeters to a few centimeters in size, so microwave wavelengths can be comparable. Microwaves are used in microwave ovens for heating food as they cause water molecules in food to vibrate and generate heat. They are also used in communication systems for transmitting information. Infrared has shorter wavelengths than microwaves and is mainly used for things like thermal imaging. Radio waves have much longer wavelengths (usually meters to kilometers). Visible light has very short wavelengths (hundreds of nanometers) and is used for vision.

Answer:

Microwaves
