What are X-rays used for?

Back

X-rays are electromagnetic waves that are absorbed by bones and are used to create medical images.

Front

What type of EM wave is used to cook food?

Back

Microwaves are used to cook food and have a higher frequency (and shorter wavelength) than radio waves.

Front

What type of wave can travel through matter or empty space?

Back

Electromagnetic Waves can travel through both matter and empty space.

Front

Which type of EM wave has the shortest wavelength and highest frequency?

Back

Gamma rays have the shortest wavelength and highest frequency, and they are extremely harmful.

Front

Which type of electromagnetic radiation has the shortest wavelength?

Back

Gamma Rays have the shortest wavelength among electromagnetic radiation.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of EM radiation, from radio waves to gamma rays.

Front

What are radio waves used for?

Back

Radio waves are used for communication, including radio and television broadcasts.

Front

What is the frequency of microwaves compared to radio waves?

Back

Microwaves have a higher frequency and shorter wavelength than radio waves.

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What are infrared waves used for?

Back

Infrared waves are used in remote controls and thermal imaging.
