Waves & Electromagnetic Spectrum

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, caused by a change in its speed.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, which includes visible light, infrared, ultraviolet, and more.

Front

What type of wave is infrared?

Back

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

Front

What happens to light when it passes through a prism?

Back

When light passes through a prism, it refracts and separates into its component colors, creating a spectrum.

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 186,282 miles per second).

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What type of waves are emitted by warm objects?

Back

Warm objects emit infrared waves, which are associated with heat.

Front

What is visible light?

Back

Visible light is the portion of the electromagnetic spectrum that can be detected by the human eye, typically ranging from 400 to 700 nanometers in wavelength.

Front

What is the role of microwaves in communication?

Back

Microwaves are used in communication technologies, such as satellite and mobile phone transmissions, due to their ability to carry information over long distances.

Front

What is ultraviolet (UV) radiation?

Back

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