Reflection of Sound
Reflection of Sound
Reflection of sound wave: Like light, sound can also be made to change its direction and bounce back when it falls on a hard surface. The bouncing back of sound when it strikes a hard surface is known as reflection of sound. The reflection of sound does not require a smooth and shining surface like that of mirror, it can be reflected from any surface whether it is smooth or rough. Sound is reflected in the same way as light and follows the same laws of reflection, which are as follows:
1. The incident sound wave (AO), the reflected sound wave (OB) and the normal (ON) at the point of incidence, all lie in the same plane.
2. The angle of incidence (<AON) of sound is equal to the angle of reflection (<NOB) of sound.

The experience was nice. I studied here for three years and saw a tremendous change in myself. I started liking subjects like English and SST which earlier I ran from. Extra knowledge gave me confidence to overcome competitive exams. One of the best institutes for secondary education.
