Electromagnetic Spectrum

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, which includes visible light, radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays.

What is frequency in the context of waves?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).

Front

How does wavelength relate to frequency?

Back

Wavelength is inversely related to frequency; as the wavelength decreases, the frequency increases.

Front

What happens to wave energy as wavelength decreases?

Back

The energy of waves increases as the wavelength gets shorter.

Front

What is wavelength?

Back

Wavelength is the distance from the peak of one wave to the peak of the next wave.

Front

What type of waves are used in microwave ovens?

Back

Microwaves are the type of waves that make water molecules vibrate and warm up.

Front

What is amplitude?

Back

Amplitude is the height of a wave from its rest position to its peak, indicating the energy of the wave.

Front

What are radio waves used for?

Back

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

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).

Front

What is the relationship between energy and frequency?

Back

Higher frequency waves carry more energy than lower frequency waves.
