Energy emitted in the form of visible radiation is called:
Correct answer: A. Light energy
- A. Light energy
- B. Sound energy
- C. Tidal energy
- D. Geothermal energy
Explanation
Light energy comes in the form of visible radiation. The energy emitted in the form of visible radiation is called light energy. Light energy refers to the energy which enables us to have a vision. It is the energy that helps us to see. We can see the radiation of light energy from the natural source of the sun and the artificial sources of bulbs and tube lights. Hence, it is the answer.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
