Sound waves go along a corridor, past an open doorway. All the waves will have the most difficulty diffracting through the doorway. Option D is correct.
What is diffraction?
Diffraction refers to a variety of events that occur when a wave collides with a barrier or an opening.
Diffraction is described as the bending of waves around the corners of an obstruction or through an aperture into the region of the obstacle's geometrical aperture's shadow.
The one with the longer wavelength will readily diffract. As a result, the one with a wavelength of 100 m can diffract readily.
Sound waves have a wavelength of 16.6 ×10⁻³ to 16.6 m in comparison to other waves. Which are audible to them, allowing them to diffract readily.
Sound waves go along a corridor, past an open doorway. All the waves will have the most difficulty diffracting through the doorway.
Hence,option D is correct.
