C) The wavelength is not affected by the temperature of the object.
Question 2
A parallel-plate capacitor is connected to a battery and becomes fully charged. The capacitor is then disconnected, and the separation between the plates is increased in such a way that no charge leaks off.
As the plates are being separated, the energy stored in this capacitor A) increases.
B) decreases.
C) does not change.
D) become zero.
