blue and green light
An insulator differs from a conductor in that an insulator
has fewer freely moving electrons
What color light is transmitted by a piece of red glass?
red
A negatively charged rod is brought near a metal conductor. The electrons in the metal conductor experience a force of
repulsion
Charge carriers in a metal are electrons rather than protons because electrons are
