Question

what energy transformation is performed by a television?
a. electrical energy to light energy
b. nuclear energy to sound energy
c. sound energy to nuclear energy
d. light energy to kinetic energy

Explanation:

A television operates on electrical energy. The screen emits light, which is light energy. So, it transforms electrical energy to light energy. Nuclear energy (options B and C) is not involved as TVs don't use nuclear reactions. Option D is incorrect as the input is not light energy.

Answer:

A. Electrical energy to light energy
