![]() ![]() By considering the gap width, wavelength, wavefront shape, obstacle size, and distance, we can predict and analyze the diffraction patterns observed in various situations, from bending light around corners to spreading sound waves through doorways. Understanding these factors helps explain the behaviour of waves when they encounter gaps or obstacles. Therefore, diffraction tends to be more prominent when the observer or the diffracting object is farther away from the source. As the distance increases, the spreading out of waves becomes more noticeable. Distance: The distance between the source of the waves and the diffracting object also affects diffraction.On the other hand, a larger barrier might cause less diffraction or even block the waves entirely. A minor block or opening allows waves to spread out more, resulting in a more pronounced diffraction effect. Obstacle Size: The size of the obstacle about the wavelength of the waves also influences diffraction.A curved wavefront, such as that produced by a spherical wave source, tends to diffract more around obstacles or through gaps. When the wavefront is a plane (flat), it diffracts differently than when it is curved. 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.
