What happens to water waves when they encounter a stone during their path? Do they turn back or they continue moving on their way? What happens to water when you put a finger under the tap? Does water turn back on the tap or it continues falling down? Is the direction of water the same as before putting the finger under the tap? Why? What does Huygens Principle say on diffraction of waves?.What is the relationship between diffraction and interference?.What happens to the shape of waves in diffraction?.What are the conditions for diffraction to occur?.They impact how we perceive sound and are essential considerations in fields such as acoustics, architecture, engineering, and the design of sound systems and concert halls.In this Physics tutorial, you will learn: These phenomena of reflection, refraction, and diffraction play a crucial role in the behavior and propagation of sound waves in various environments. For example, if you hear someone's voice from behind a wall, the sound waves diffract around the corners of the wall, allowing you to perceive the sound. This phenomenon allows sound to be heard even if the sound source is not directly visible. When sound waves encounter an obstruction or opening, they diffract, meaning they bend around the edges of the obstacle or opening and spread out. Refraction can have significant effects on the transmission of sound, such as the bending of sound around obstacles or the focusing of sound in specific directions.ĭiffraction is the bending or spreading out of sound waves as they encounter an obstacle or pass through an opening that is comparable in size to their wavelength. This bending of sound waves is due to the variation in their speed as they move from one medium to another. When sound waves encounter a medium with different characteristics, their speed changes, causing the waves to change direction. Refraction refers to the bending or changes in the direction of sound waves as they pass from one medium to another with different properties, such as density or temperature. Reflective surfaces, such as walls, floors, and ceilings, can affect the acoustics of a room by reflecting or absorbing sound waves. For example, when sound waves reflect off a solid wall or a mountain, they reach our ears after bouncing back, creating a distinct echo. This phenomenon allows us to hear echoes. The angle of incidence (the angle at which the sound wave strikes the surface) is equal to the angle of reflection (the angle at which the sound wave reflects off the surface). Reflection occurs when sound waves encounter a boundary or obstacle and bounce back. Let's explore each of these phenomena in relation to sound waves: Sound waves exhibit reflection, refraction, and diffraction, just like other types of waves.
