Planck's Relationship

Instructions: Read each question carefully. Choose the answer that best fits the question. Short answer response questions must be responded to in complete sentences. If the question involves calculations, you must show all your math work.

Planck's relation describes the proportionality constant between the energy of a charged atomic oscillator in the wall of a black body, and the                 of its associated electromagnetic wave.
