Question: Can light bend around corners

Parnika Gupta answered on 9 Nov 2020:

Yes, light can bend around corners. In fact, light always bends around corners to some extent. This is a basic property of light and all other waves. The amount of light that bends around a corner depends on the exact situation. For visible light on the human scale, the amount of light that bends around corners is often too small to notice unless you know how to look for it. The ability of light to bend around corners is also known as “diffraction”.
