Whether the phenomenon of bending of sound waves around columns in large concert halls is result of refraction or diffraction.
Explanation of Solution
Introduction:
The phenomenon of bending of a wave when an obstacle comes in its way is called diffraction, while refraction is bending of light when it enters in another medium from one medium.
In a concert hall, the bending of sound wave is an example of diffraction of wave because it passes around the column. Here, column acts as an obstacle. Since there is no change in medium of propagation, it is not refraction.
Conclusion:
Thus, the bending of sound waves around columns in large concert halls is result of diffraction.
