Respuesta :

A mechanical wave is an oscillation of matter so they carry and transfer energy through a medium but they don't transfer matter themselves. They can be longitudinal or transverse. So Choice B is false.

The answer option which not true about mechanical waves is: B. they transfer matter.

A wave can be defined as a disturbance in a medium that progressively transports energy from its source to another location, without the transfer (transportation) of matter.

In Science (Physics), there are two main (2) types of wave and these are:

  • Electromagnetic wave: it is a wave that do not require a medium for its propagation and it can travel through a vacuum (empty space).
  • Mechanical wave: it is a wave that requires a medium for its propagation.

Some of the properties or characteristics of mechanical waves include the following:

I. Mechanical waves generally carry energy.

II. Mechanical waves can be longitudinal in nature.

III. Mechanical waves require a medium of propagation.

IV. Mechanical waves do not transfer matter.

In conclusion, both electromagnetic and mechanical waves do not transfer matter at all.
