Question

A tuning fork is struck against a hard surface. The particles in the tuning fork begin to vibrate quickly, transmitting a wave. What kind of wave does the tuning fork transmit?
seismic wave

mechanical wave<- I was thinking this one but i'm not sure, please help!

electromagnetic wave

radio wave

Answer 1

Answer:

Mechanical waves

Explanation:

Waves are classified into two types:

- Electromagnetic waves: these waves are oscillations of the electric and magnetic fields in a direction perpendicular to the motion of the wave. They all travel at the speed of light in a vacuum, and they are the only waves able to travel through a vacuum. Examples of electromagnetic waves are visible light, radio waves, microwaves..

- Mechanical waves: these waves are produced by the oscillations of the particles in a medium. Due to their nature, they cannot travel in a vacuum, since there is no medium. Examples of mechanical waves are: sound waves, seismic waves, etc.

In this problem, the tuning fork is struck against a hard surface; as we know, the particles in the tuning force begin to vibrate quickly, causing vibrations in the particles in the air. These are sound waves: sound waves are mechanical waves (because they are produced by the vibrations of the particles in the medium), therefore the correct answer is

Mechanical wave
