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.

Front

What happens to the frequency of a wave as the wavelength decreases?

Back

As the wavelength decreases, the frequency increases.

Front

What is a transparent object?

Back

A transparent object is one that allows all light to pass through, enabling clear visibility of objects behind it.

Front

What is a prism?

Back

A prism is a transparent object with refracting surfaces that separates white light into a spectrum of colors.

Front

Which type of electromagnetic radiation has the shortest wavelength?

Back

Gamma rays have the shortest wavelength in the electromagnetic spectrum.

Front

What is the difference between transparent, translucent, and opaque materials?

Back

Transparent materials allow all light to pass through, translucent materials allow some light to pass but scatter it, and opaque materials do not allow any light to pass through.

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 (or about 300,000 kilometers per second).

Front

What is infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves, commonly associated with heat.

Front

What is ultraviolet radiation?

Back

Ultraviolet radiation is a type of electromagnetic radiation with wavelengths shorter than visible light, known for its ability to cause sunburn.

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.
