Front

What is the range of electromagnetic radiation that is visible to the human eye?

Back

Visible Light

Front

What does a blackbody radiation curve represent?

Back

It represents the intensity of radiation emitted by a blackbody at different wavelengths.

Front

What is the phenomenon called when light from an object moving away from an observer is shifted to longer wavelengths?

Back

Redshift

Front

What is the relationship between the temperature of an object and the peak wavelength of its emitted radiation?

Back

Wien's Displacement Law states that the peak wavelength is inversely proportional to the temperature.

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 the significance of the visible spectrum in terms of human perception?

Back

The visible spectrum is the portion of the electromagnetic spectrum that can be detected by the human eye, allowing us to see colors.

Front

How does the Doppler effect relate to light?

Back

The Doppler effect describes the change in frequency or wavelength of light from a source moving relative to an observer.

Front

What is a blackbody?

Back

A blackbody is an idealized physical object that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence.

Front

What is the formula for calculating the energy of a photon?

Back

E = hf, where E is energy, h is Planck's constant, and f is frequency.
