Question 7

Can mechanical waves travel from the Sun to Earth? Explain your answer.

•No because the distance is too far.

•Yes because mechanical waves can travel through anything.

•No because mechanical waves must have a medium to travel through.

•Yes because light waves are mechanical waves.

The correct answer is :

No because mechanical waves must have a medium to travel through.

Explanation:

Mechanical waves :

These are the waves which require a medium to propagate through. This is so because energy from one point to another point  is transferred with the help of particles present in the medium.These speed of mechanical,waves is fastest in solids, faster in liquids and fast in gases. Sound is the most common example of mechanical wave.

Electromagnetic waves :

These are the waves which does not require a medium to propagate through and they can also travel through vacuum. These waves have electrical and magnetic fields vibrating perpendicular to each other. Sun light is an example of electromagnetic wave.

No, mechanical waves cannot travel from the Sun to Earth because mechanical waves must have a medium to travel through.

jjj89t'ji; it hink the answer is your mom is not si

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
