Here's why:

* Law of Reflection: This law states that the angle of incidence (angle between the incoming wave and the normal to the reflecting surface) is equal to the angle of reflection (angle between the reflected wave and the normal). This law is based on the principle of reversibility of light, which applies to both transverse and longitudinal waves.

* Transverse Waves: These waves have oscillations perpendicular to the direction of wave propagation. Examples include light waves, water waves, and waves on a string.

* Longitudinal Waves: These waves have oscillations parallel to the direction of wave propagation. Examples include sound waves and seismic waves.

How reflection works for both types:

Both types of waves undergo a change in direction when they encounter a boundary between two mediums. This change in direction is governed by the law of reflection, which applies regardless of whether the wave is transverse or longitudinal.

Key point: The nature of the wave (transverse or longitudinal) determines how the wave *propagates*, but the law of reflection governs how the wave *bounces* off a surface.
