Energy Review

Front

What is absorption in terms of light?

Back

Absorption is the process by which light is taken in by a material, converting the light energy into other forms of energy, such as heat.

Front

List the electromagnetic waves in order of decreasing frequency.

Back

Gamma rays, X-rays, Ultraviolet rays, Visible light, Infrared rays, Microwaves, Radio waves.

Front

What is the relationship between wavelength and frequency?

Back

A wave with a large wavelength has a low frequency and low energy.

Front

What type of electromagnetic wave causes sunburns?

Back

Ultraviolet (UV) rays.

Front

What is radiation in the context of heat transfer?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation from heat lamps.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

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 electromagnetic spectrum?

Back

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

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 wavelengths of about 400 to 700 nanometers.
