Radiation

Front

What is radiation?

Back

Radiation is the emission or transmission of energy in the form of waves or particles through space or a medium.

Front

How can light (radiation) be described?

Back

Light can be described as having properties of both a wave and a particle.

Front

What is a blackbody curve?

Back

A blackbody curve is a graph that shows how an object emits radiation over different frequencies.

Front

What is wavelength?

Back

Wavelength is the distance between crest to crest of a wave or the time it takes for one complete cycle to pass.

Front

What is the range of visible light in nanometers?

Back

Visible light ranges from about 400 nanometers (blue) to around 700 nanometers (red).

Front

What is frequency in relation to waves?

Back

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

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is Wien's Law?

Back

Wien's Law states that the wavelength of the peak emission of a blackbody is inversely proportional to its temperature.

Front

What is Stefan's Law?

Back

Stefan's Law states that the total energy radiated per unit surface area of a blackbody is proportional to the fourth power of its temperature.

Front

What is electromagnetic radiation?

Back

Electromagnetic radiation is a form of energy that travels through space at the speed of light and includes visible light, radio waves, X-rays, and more.
