Why does not refraction take place in a rectangular glass slab |
| Answer» When light passes through glass, it encounters two interfaces,one entering and the other leaving. It slows down at the first interface and speeds back up at the second. If the two interface surfaces are parallel to each other, as in a \'slab\' of glass, all of the bending (refraction) that takes place at the first interfaces is exactly reversed at the second, \'undoing\' the effect of the first interface, so although the emerging ray of light is displaced slightly from the entering ray, it travels in the same direction as the incoming ray .So we can\'t see the refraction.The path of light is from air to glass and then again glass to air . | |
