Question

Match the description to the type of energy.

(1)diaphragm vibrations

(2) Changing magnetic fields

(3)sound waves
———————————
(A)sound waves

(B)electrical energy

(C)mechanical energy

Answer 1

1)diaphragm vibrations- sound waves

2) Changing magnetic fields- Electrical energy

3)sound waves- Mechanical energy

Step-by-step explanation:

A changing magnetic field induces an electromotive force and then an electric field which contains electrical energy

Sound energy is a form of energy that can be heard by humans. Sound is an example of a mechanical wave because it consists of physically oscillatory elastic compression.

A diaphragm is a thin surfaced cone used to produce sound. It is caused to vibrate using electromagnetic energy.
