Longitudinal waves involve changes in volume and density of the medium. Since all media can sustain compressive stress, longitudinal waves can be transmitted through all the three types of media.

Longitudinal waves
Longitudinal waves are waves in which the particles of the medium vibrate in the same direction as the wave is propagating. These waves can be transmitted through solids, liquids, and gases.
Explanation:
- Definition of longitudinal waves: Longitudinal waves are a type of mechanical wave in which the particles of the medium move parallel to the direction of energy transfer. This means that the particles oscillate back and forth in the same direction as the wave is moving.
- Propagation through solids: Longitudinal waves can propagate through solids because the particles in solids are closely packed and can easily transmit the energy of the wave from one particle to another. Examples of longitudinal waves that can propagate through solids include sound waves and seismic waves.
- Propagation through liquids: Longitudinal waves can also propagate through liquids. Although the particles in liquids are not as closely packed as in solids, they are still able to transmit the energy of the wave through their interactions. Sound waves can propagate through liquids such as water.
- Propagation through gases: Longitudinal waves can also propagate through gases. In gases, the particles are much farther apart compared to solids and liquids, but they can still transmit the energy of the wave through their collisions. Sound waves are examples of longitudinal waves that can propagate through gases such as air.
- Transverse waves: Unlike longitudinal waves, transverse waves are waves in which the particles of the medium vibrate perpendicular to the direction of energy transfer. Transverse waves cannot propagate through gases because the particles in gases do not have a fixed position and cannot transmit the energy of the wave in a perpendicular direction.
- Electromagnetic waves: Electromagnetic waves are not mechanical waves and do not require a medium to propagate. They can travel through empty space as well as through solids, liquids, and gases. Electromagnetic waves include light waves, radio waves, microwaves, and X-rays.
Therefore, the correct answer is option D: Longitudinal waves.
