2.1 Sun's 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.

Front

What are infrared waves?

Back

Infrared waves are a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves. They are often associated with heat.

Front

What is the order of the electromagnetic spectrum from shortest to longest wavelength?

Back

The order from shortest to longest wavelength is: gamma rays, X-rays, ultraviolet, visible light, infrared, microwaves, radio waves.

Front

What type of radiation has the highest energy?

Back

Gamma rays have the highest energy in the electromagnetic spectrum.

Front

What type of radiation causes sunburns?

Back

Ultraviolet (UV) radiation causes sunburns.

Front

How does wavelength relate to frequency and energy?

Back

As wavelength gets shorter, frequency and energy increase.

Front

What are microwaves used for?

Back

Microwaves are used for cooking food, in communication technologies, and in radar.

Front

What is visible light?

Back

Visible light is the part of the electromagnetic spectrum that can be seen by the human eye, with wavelengths ranging from approximately 400 to 700 nanometers.

Front

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

Back

Higher frequency electromagnetic waves have more energy than lower frequency waves.

Front

What are radio waves?

Back

Radio waves are a type of electromagnetic radiation with the longest wavelengths, used for communication such as radio and television signals.
