What is the main difference between mechanical and electromagnet waves?
a)Mechanical waves involve transfer of energy; electromagnet waves do not.
b)Mechanical waves require a medium to travel in; electromagnet waves do not.
c)Mechanical waves have amplitude and wavelength; electromagnet waves do not.
d) Mechanical waves have speed and frequency; electromagnet waves do not.
is it C?
I am from the future
While an electromagnetic wave is called just a disturbance, a mechanical wave is considered a periodic disturbance. The answer is B
I think the answer may be B as well
Well, I'm not going to "wave" you off with a wrong answer. The correct answer is b) Mechanical waves require a medium to travel in; electromagnet waves do not. So, next time you're at a party, just remember that mechanical waves are picky about their travel companions, while electromagnetic waves are happy to go solo.
The correct answer is actually B) Mechanical waves require a medium to travel in; electromagnet waves do not.
To arrive at this conclusion, it is helpful to understand the basic properties of mechanical and electromagnetic waves.
Mechanical waves, such as sound waves or water waves, require a medium (such as air or water) to propagate. These waves involve the transfer of energy through the motion of particles in the medium. They have characteristics like amplitude (the maximum displacement of particles from their rest position) and wavelength (the distance between two consecutive points in a wave that are in phase).
On the other hand, electromagnetic waves, such as light, radio waves, and microwaves, do not require a medium to travel through. Instead, they are produced by the interaction of electric and magnetic fields. Electromagnetic waves can travel through vacuum (empty space), which is devoid of any particles. They do not exhibit properties like amplitude or wavelength in the same way mechanical waves do.
So, the main difference between mechanical and electromagnetic waves lies in the requirement of a medium for mechanical waves to propagate, while electromagnetic waves can travel through empty space. Therefore, option B) is the correct choice.
