A flashlight does not produce sound energy; it emits light energy. Devices like televisions, radios, and phones have speakers to create sound, but a flashlight does not have the necessary components to produce sound waves.
The object that does NOT produce sound energy among the options provided is c. flashlight. Televisions, radios, and phones are all devices that produce sound for communication or entertainment purposes. A flashlight, on the other hand, emits light energy and does not have components designed to produce sound.
Sound energy is generated by vibrations in objects which create sound waves. These waves require a medium, like air or water, to travel through. In contrast, a flashlight produces light waves which are electromagnetic waves and can travel through a vacuum unlike sound waves. Light waves do not require a physical medium to propagate. The three devices that produce sound (television, radio, phone) have speakers that convert electrical signals into vibrations, thus creating sound. However, a flashlight utilizes a light bulb or LED to convert electrical energy directly into visible light energy without the production of sound.
