Which device converts sound waves to electrical signals?

Which device converts sound waves to electrical signals? Correct Answer Microphone

The Correct Answer is Option 3 i.e Microphone.

Key Points

  • Microphone: Converts a sound wave into an electrical signal.
  • Loudspeaker: Converts an electrical signal into sound waves.
  • Headphone: Converts electrical energy into mechanical energy to produce sound. 
  • Amplifier: 
    • It is used to change the amplitude of a signal.
    • The purpose of an amplifier is to produce an output signal larger than that of the input signal.
    • It is used to convert Direct current into Alternate Current.

In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: As the source continues to vibrate the medium, the vibrations propagate away from the source at the speed of sound, thus forming the sound wave. B: The sound source creates vibrations in the surrounding medium.  C: The sound waves are generated by a sound source, such as the vibrating diaphragm of a stereo speaker. D: Sound can propagate through a medium such as air, water, and solids as longitudinal waves and also as a transverse wave in solids.

The human eye is a complex part of the body that is used for seeing. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight, or vision, is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. When someone looks at an object, what he really sees is the light reflected from the object. This reflected light passes through the lens and falls on the retina of the eye. Here the light induces nerve impulses that travel through the optic nerve to the brain and then over other nerves to muscles and glands.
The eye is similar to a television camera. Both the eye and the television camera convert light energy to electrical energy. The eye converts light to nerve impulses that are interpreted by the brain as the sense perception called sight. A television camera converts light to electronic signals that are broadcast and transformed into light images in a television receiver. It is wonderful that human eyes blink an average of once every six seconds. This washes the eye with the salty secretion from the tear or lachrymal glands. Each tear gland is about the size and shape of an almond. These glands are situated behind the upper eyelid at the outer corner of the eye. After passing over the eye, the liquid from the gland is drained into the nose through the tear duct at the inner corner of the eye. The sense perception that the brain releases after the eye converts light to nerve impulses is known as
