What best describes the waves produced by the tuning fork?

Electromagnetic waves are produced by the electric field and magnetic field vibrating perpendicular to each other. Electromagnetic waves can travel through space and medium. A tuning fork vibrates the air around it. The vibrating fork produces mechanical waves.

Which best describes what is required for any sound wave to travel?

Sound has to travel through some sort of medium. Any medium will do. Sound can not travel through the Vacuum of space.

What is rarefaction in terms of pressure?

Rarefactions are areas of ultrasound wave having low pressure as the distance of their particles is far while compressions are areas having high pressure as the distance of their particles is close.

Can a sound wave travel in a vacuum?

Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.

What do you mean echo?

An echo is a repetition or imitation of sound. When sound waves hit a hard surface they might reflect, making the sound bounce and repeat. If you agree with someone, you might echo his or her statement.

What is Echo Short answer?

In linguistics, an echo answer or echo response is a way of answering a polar question without using words for yes and no. The verb used in the question is simply echoed in the answer, negated if the answer has a negative truth-value. For example: “Did you go to the cinema?” (or “Didn’t you go to the cinema?”)

Is Echo better than Google?

The Echo has been our Editors’ Choice for a long time, and it still has a few advantages, like being able to use multiple wake words. But over the past year, the Google Home has become less expensive, and we feel like Google Assistant has pulled ahead, making the Home a better choice right now.

What are the causes of echo?

An echo is a sound that is repeated because the sound waves are reflected back. Sound waves can bounce off smooth, hard objects in the same way as a rubber ball bounces off the ground. Although the direction of the sound changes, the echo sounds the same as the original sound.
