Diffraction is commom in sound but not commom in light waves ? Why ? |
| Answer» Solution :Diffraction effect is more pronounced if the SIZE of obstacle or APERTURE is of the order of the wavelength of waves. As the wavelength of light `(10^-8m)` is much SMALLER than the size of the objects around SOUND so, diffraction of light is not easily SEEN. But sound waves have large wavelength. They get easily diffracted by the objects around us. | |
