An obstacle of large size, which may be polished or rough, is needed for the reflection of sound waves.

The incident sound, reflected sound, and surface normal all lie in the same plane.

Both the incident and reflected sound waves make equal angles with the normal to the reflecting surface at the point of incidence.

Like light, sound follows the laws of reflection, where the incident and reflected sound make equal angles with the surface normal.

Sound bounces off a solid or liquid surface, similar to how a rubber ball bounces off a wall.

The speed of sound varies at different temperatures within a medium, increasing as temperature rises due to increased molecular motion.

Yes, in air, the speed of sound is 331 m/s at 0°C and 344 m/s at 22°C.

Increasing the temperature of a medium generally increases the speed of sound.

The speed of sound decreases as we transition from a solid to a gaseous state.

Sound travels at a much slower speed than light, causing a delay between seeing the flash and hearing the thunder.
