Final answer:
In a computer monitor, electrical energy is transformed into light energy to display images and into sound energy if the monitor has speakers, in accordance with the law of conservation of energy.
Step-by-step explanation:
The correct answer is option electrical energy is changed to light energy and sound energy in a computer monitor. When we discuss how a monitor works, it involves converting the electrical energy that powers the device into light energy to display images and into sound energy if the monitor has built-in speakers.
This process is an example of energy transformation, where one form of energy is converted into another form through work or heat, as is consistent with the law of conservation of energy.
In simpler terms, the monitor takes electricity from the power outlet and uses it to create the images you see on the screen (light energy) and any sounds it emits through speakers (sound energy). This transformation is fundamental to how monitors and many other electronic devices operate.
In a computer monitor, electrical energy is changed to radiant energy (light energy) and sound energy.
Electrical energy from the power source is converted into radiant energy in the form of light by the screen of the computer monitor. This allows us to see the images on the screen. Additionally, the monitor speakers convert electrical energy into sound energy, allowing us to hear audio from the computer
