😳 WHY? ❓❓
Why does a straw look bent in a glass of water?
Light travels faster in air than in water. When light from the part of the straw under water passes from water into air on its way to our eyes, it speeds up and changes direction slightly at the surface. This bending of light is called refraction. Our brain assumes light always travels in straight lines, so it traces the rays back along the wrong path and “sees” the underwater part of the straw a little higher and shifted from where it really is. That is why the straw seems broken or bent at the water’s surface, and why a pool or pond also looks shallower than it actually is.
