An object emits a range of electromagnetic energy wavelengths because
A)not all molecules vibrate at the same speed.
B)relativity theory states that objects attain varying terminal velocities.
C)lowest and highest vibration rates are cancelled.
D)all molecules vibrate at the same rate.

Question

Quizplus · Accepted Answer

The range of electromagnetic energy wavelengths emitted by an object is dependent on the varying speeds at which the molecules within the object are vibrating. This causes a range of energies to be emitted, resulting in a spectrum of electromagnetic radiation. Therefore, choice A is the best choice.
