Im sorry i am totally stumped

What is the main difference between mechanical and electromagnetic waves
A. Mechanical waves involve the transfer of energy; electromagnetic waves do not

B. Mechanical waves require a medium to travel in; electromagnetic waves do not

C. Mechanical waves have amplitude and wavelength; electromagnets waves do not

D. Mechanical waves have speed and frequency; electromagnetic waves do not.

Plz help ;-;

I think it is maybe B?

Ok almost 3k and.None of his family answered still the salons go to them and then I said eaten all my God I’m like toast see you he he I will eat I’m gonna eat or Mars and then say

No problem, I'm here to help! To find the answer to your question about the main difference between mechanical and electromagnetic waves, we can go through the options one by one.

A. Mechanical waves involve the transfer of energy; electromagnetic waves do not.
This option is not correct. Both mechanical waves and electromagnetic waves involve the transfer of energy. So we can eliminate option A.

B. Mechanical waves require a medium to travel in; electromagnetic waves do not.
This option is correct. Mechanical waves, such as sound waves and water waves, require a medium (such as air or water) to travel through. On the other hand, electromagnetic waves, such as light waves and radio waves, can travel through a vacuum, which means they do not require a medium. So option B is the main difference between mechanical and electromagnetic waves.

C. Mechanical waves have amplitude and wavelength; electromagnetic waves do not.
This option is not correct. Both mechanical waves and electromagnetic waves have properties such as amplitude (the magnitude of the wave) and wavelength (the distance between two consecutive points of similar characteristics on the wave). So we can eliminate option C.

D. Mechanical waves have speed and frequency; electromagnetic waves do not.
This option is not correct either. Both mechanical waves and electromagnetic waves have speed (the rate at which the wave propagates through space) and frequency (the number of oscillations or cycles per second). So we can eliminate option D.

In conclusion, the main difference between mechanical and electromagnetic waves is that mechanical waves require a medium to travel through, while electromagnetic waves do not. Therefore, the correct answer is option B. I hope this clarifies things for you!

It is B

electromagnetic wave

waves that transfer electromagnetic energy
electromagnetic wave
A wave made up of a combination of changing eletic field and a changing magnetic field.
mechanical wave
a wave that requires a medium through which to travel
I would think B
