Definition

Amplify means to increase the size or strength of something. In science, amplify is used to describe how scientists increase the size or strength of sounds, signals, or other waves.

This can be done using a variety of devices, such as amplifiers, speakers, and telescopes. Amplifiers increase the amplitude of a wave, which is the measure of its size or strength. Speakers convert electrical signals into sound waves, which can then be amplified to make them louder. Telescopes collect and focus electromagnetic radiation, such as light, which can then be amplified to make it easier to see.

The process of amplification is often used in scientific experiments to make small or weak signals easier to measure or observe. For example, scientists might use an amplifier to increase the signal from a heart monitor so that they can more easily see the heartbeat on a screen.

Here are some examples of how amplify is used in science:

  • Amplifiers are used in sound systems to make music louder
  • Speakers are used in computers and other devices to amplify sound
  • Telescopes are used to amplify light from distant objects
  • Radio telescopes are used to amplify radio waves from space
  • Magnetic resonance imaging (MRI) machines use amplifiers to amplify the signals from the body so that doctors can see the internal structures of the body more clearly

How can the word be used?

The telescope amplified the light from the stars, making them appear brighter.

amplify

Different forms of the word

Verb: amplify, amplifies, amplified, amplifying.

Adjective: amplifying.

Noun: amplification.

Adverb: amplifyingly.

Etymology

The word "amplify" comes from the Latin word amplifico, which means "to make large or great." The word amplifico is made up of the prefix ampli, which means "large," and the verb facere, which means "to make.".

AQA Science Exam Question and Answer

Question:

How can the process of amplification be used to improve the quality of sound?

Answer:

  • The process of amplification can be used to improve the quality of sound by increasing the amplitude of the sound waves. This means that the sound waves become larger, which makes them louder and easier to hear.
  • Amplifiers can be used in a variety of ways to improve the quality of sound. For example, they can be used to amplify the sound from a microphone, which can then be used to make a speech or presentation louder. They can also be used to amplify the sound from a musical instrument, which can then be used to make the music louder and more powerful.
  • In addition to increasing the amplitude of the sound waves, amplifiers can also be used to improve the quality of sound by reducing the noise. Noise is any unwanted sound that can interfere with the desired sound. Amplifiers can be used to filter out the noise, which can make the sound clearer and easier to hear.
  • The process of amplification can be used to improve the quality of sound in a variety of settings, such as concert halls, theatres, and recording studios. It can also be used to improve the quality of sound in everyday devices, such as radios, televisions, and smartphones.
