1. The minimum time interval required between the original sound and its echo to perceive a distinct echo is 0.1 seconds. This allows the brain to differentiate between the two separate sounds.

  2. An echo is a reflected sound wave that is heard after the original sound. It occurs when the sound wave bounces off a surface and returns to the listener with a perceptible delay.

    The reflection of sound involves the bouncing back of sound waves from surfaces, often resulting in echoes, and depends on the medium’s properties and surface texture. The reflection of light involves light waves reflecting off surfaces, obeying the law of reflection (angle of incidence equals angle of reflection), and is influenced by the surface’s smoothness and reflectivity.

  4. In sound reflection, the angle of incidence equals the angle of reflection, similar to light reflection. This means that the sound wave striking a surface at a certain angle will reflect off the surface at the same angle but in the opposite direction, following the law of reflection.

  5. Sound interacts with solid or liquid surfaces by reflecting, refracting, or absorbing. Reflected sound creates echoes, refraction alters its path through different media, and absorption diminishes its energy, converting it to heat.
