We can hear sounds around corners but we cannot see around corners; yet both sound and light are waves. Explain the difference.
Step 1 of 1
When the waves pass through an opening they undergo diffraction. The amount of diffraction depends on proportion. is wavelength of the waves, a is the width of the opening. Then, the longer the wavelength the bigger the proportion so diffraction. Since the wavelength of the sound waves is longer than light waves, the sound waves passing around the corner undergo more diffraction than light. That’s why we can hear the sound cannot see the light that well.
