They purchased the single ticket and decided that A would be in the hall during the 1st half and B during the 2nd half.Both of them reached the hall together. But unfortunately only one ticket was left. Read the following text and answer the following questions on the basis of the same:Diffraction in a hall:A and B went to purchase a ticket of a music programme. Understanding the principles of diffraction in sound waves can help us design better sound systems and optimize their performance. Thus, diffraction is a fundamental property of sound waves that plays a crucial role in several applications, such as soundproofing, acoustic design, and music production. When sound waves encounter an obstacle with a curved surface, they diffract around the curved surface and create a sound shadow zone behind the obstacle. When sound waves encounter a sharp edge of an obstacle, they diffract and spread out into the region behind the obstacle, creating a shadow zone where the sound intensity is lower. When sound waves pass through a narrow slit or aperture, they diffract and create a series of interference patterns on a screen placed behind the slit. The larger the wavelength, the more significant the diffraction.ĭiffraction can be observed in several scenarios, such as: The amount of diffraction depends on the size of the obstacle or aperture and the wavelength of the sound wave. When sound waves travel through a medium, they move in a straight line, but when they encounter an obstacle or a small aperture, they bend or diffract around the edges of the obstacle. This bending of sound waves around the corners or edges of an obstacle is called diffraction. When a sound wave encounters an obstacle or passes through a small aperture, it bends around the edges and spreads out into the region behind the obstacle. Yes, phenomena of diffraction can occur in sound waves.
