Wavefront Shape: The shape of the wavefront, which represents the crests or troughs of a wave, also affects diffraction.The gap size (compared to the wavelength) influences the extent of waves spread - Image Source: Save my exams. Sound waves are more likely to exhibit noticeable diffraction effects in everyday situations. Longer wavelengths, like those of sound waves, diffract more than shorter wavelengths, like those of light waves. Wavelength: The wavelength of the waves is another critical factor.The wave spreads through a narrow gap - Image Source: Save my exams. A narrower gap allows waves to spread more, resulting in a more noticeable diffraction pattern. Significant diffraction occurs if the gap is narrower compared to the wavelength of the waves, such as light or sound waves. Gap Width: The width of the gap or the size of the obstacle plays a crucial role in diffraction.Several factors influence the extent and characteristics of diffraction.

However, the diffraction effect becomes less pronounced if the crack is much larger or smaller than the wavelength.ĭiffraction is an essential concept in physics as it helps explain various phenomena, such as the spreading of sound waves around corners, the behaviour of light around obstacles, and the interference patterns observed in experiments involving waves. Significant diffraction occurs if the opening or barrier is similar in size to the wavelength, causing a noticeable spreading of the waves. The extent of diffraction depends on the size of the gap or obstacle relative to the wavelength of the waves. As a result, the waves 'bend' and create a new wave pattern beyond the hole or barrier. This is spreading out because different parts of the wavefront experience different amounts of obstruction or interference as they pass through the gap or around the obstacle. Instead, they bend or 'diffract' around the edges, spreading out of the wave pattern. When waves encounter an opening or the edge of a barrier, they don't simply stop or continue in a straight line. sound wave travel around corners this is example of diffraction.Diffraction of waves refers to the phenomenon where waves spread out and change direction as they pass through a gap or around an obstacle. so diffraction easily observe in sound wave. Wavelength of light less than sound wave, so diffraction is more in longer wavelength. for audible sound normally obstacles are opening have small dimensions so d diffractions normally observed for daily life for sound wave. Frequency of the audible sound range 20Hz to 20 kilohertz, speed of sound in air 332 m per second then wavelength of audible sound greater than 1.6 cm and less than 16 m. If d >wavelength diffraction effects are almost negligible if dimension of the opening obstacle greater than the wavelength of the wave.

condition: dimension of obstacle opening comparable or smaller than the wavelength of the wave, d less than or equal to wavelength.

diffraction is a characteristic property of wave motion and all kinds of waves exhibit diffraction. when plane wavefront passed through a pinhole then it becomes a spherical wavefront and pinhole behave like point source. shape of wave change when meets an obstacle or opening in its path bending of the wave around the edge from an obstacle or an opening is called diffraction. Wave spread in medium or in space when wave created by vibrating source if medium is homogenous and isotropic then wavefront of point source is spherical wave, at long distance this wavefront became plane wave.
