Match the Physical Law or Activity Below with the Observable

Question 33

Matching

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

Premises:

Responses:

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

agitation and collision of atoms

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

the Doppler effect

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

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.

Wien's Law

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

the Stefan-Boltzmann law
