When a musician plays music on a guitar, light energy is transformed into sound energy. True or False
Answers
Answer:
Explanation:
Generally sound is produced by vibrating objects. For example, vibrating strings of musical instruments, vibrating diaphragms of drums, speakers etc. In most of the it is the mechanical energy that is converted into sound. The conversion may not be direct. The mechanical energy used to pluck a string can get stored as potential energy and gradually get converted to sound.
In a speaker, it is the electrical energy from the output amplifiers that drive the speaker coils. This gets stored as magnetic field and eventually causes vibrations producing the sound.
In a waterfalls the gravitational potential energy of the water at higher altitude gets converted into kinetic energy of water. This on impact with rocks can create sound
