Match the Physical Law or Activity Below with the Observable

Question 44

Matching

Match the physical law or activity below with the observable effect it produces.

Premises:

Responses:

An excited atom in which an electron is raised to a higher orbit.

the Stefan-Boltzmann law

The energy output of a surface is proportional to the temperature of the surface.

Wien's Law

Each atom absorbs or emits a set of photon wavelengths unique to its element type.

the Doppler effect

The wavelength of maximum intensity depends on the surface temperature of the star.

electron motion between energy levels

The apparent change in the wavelength of a photon from a source caused by the relative motion of the source and the observer.

agitation and collision of atoms
