Sound can travel around corners due to diffraction, which allows longer wavelengths, like those of sound, to bend around obstacles. In contrast, light waves have shorter wavelengths and cannot diffract as effectively, preventing us from seeing around corners. The discussion highlights that diffraction depends on the relationship between the wavelength of the wave and the size of the obstacle. While sound waves can navigate around larger objects, light waves are significantly hindered by them. Understanding these principles clarifies why we can hear sounds from around corners but cannot see.
