Question
What energy transformation is performed by a television?A.Light energy to kinetic energyB.Electrical energy to light energyC.Sound energy to nuclear energyD.Nuclear energy to sound energy
Solution
The energy transformation performed by a television is B. Electrical energy to light energy.
Here's the step by step process:
- When you plug in your television and turn it on, it receives electrical energy from the power source (the wall outlet).
- The television then converts this electrical energy into two types of energy: light and sound.
- The light energy is used to create the images you see on the screen.
- The sound energy is used to produce the audio you hear from the speakers.
- Therefore, the correct answer is B. Electrical energy to light energy (and sound energy).
