EM Spectrum

Gamma rays are high-energy electromagnetic waves emitted by radioactive materials.

Gamma rays have the greatest frequency in the electromagnetic spectrum.

The wavelength of light determines its color.

Frequency is the number of waves that pass a point in one second.

Radio waves are used to send signals, including WiFi and text messages.

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

Wavelength and frequency are inversely related; as wavelength increases, frequency decreases.

X-rays are used in medical imaging.

The speed of light in a vacuum is approximately 299,792 kilometers per second (or about 300,000 km/s).

Microwaves are commonly used for cooking food and in communication technologies.
