      Both sound and light adhere to the laws of reflection, although their behaviors differ due to their distinct properties.

      Shared Principle:

      1. Angle of Incidence Equals Angle of Reflection: Similar to light waves, sound waves obey the law that the angle at which the wave encounters a surface (angle of incidence) equals the angle at which it rebounds off that surface (angle of reflection).

      Divergence:

      1. Medium of Propagation: Sound necessitates a physical medium (like air, water, or solids) for transmission, while light can propagate through vacuum or transparent materials.

      2. Speed Disparity: Sound travels slower than light, impacting how waves interact with surfaces. Sound waves reflect off surfaces capable of vibration, causing the sound to echo or reverberate.

      3. Wavelengths and Frequencies: Sound waves possess longer wavelengths and lower frequencies compared to light waves, influencing how they interact during reflection.

      4. Interference Effects: Sound waves can produce interference patterns, influencing how they reflect off surfaces, particularly within enclosed spaces.

      In essence, both sound and light waves conform to the principle of reflection concerning the incident and reflected angles. However, their individual properties dictate differing behaviors in how they interact with various surfaces in our surroundings.
