Which of the following statements does NOT accurately describe mechanical waves

Mechanical waves are transverse or longitudinal.


Mechanical waves do not require a medium.


Mechanical waves transmit energy.


Mechanical waves include sound waves.

Mechanical waves do not require a medium. IS NOT CORRECT
bcoz mechanical waves need medium for their propagation

"Mechanical waves do not require a medium" doesn't, because mechanical waves must travel through the medium of matter, unlike electromagnetic (radio, light, etc etc.) waves, which can travel through a vacuum.

Mechanical waves can be either transverse or longitudinal
All waves transmit energy.
Sound waves are mechanical longitudinal waves that can be detected by the ear
