Question

We can see our reflection in water also that mean in water also reflection but when we try to touch it is become unstable

Answer 1

Regular reflection occurs on smooth surfaces which does not have any irregularities.The surface of water if left undisturbed also becomes smooth.When a ray of light strikes an object , apart of reflected and part of it is absorbed. So when light falls on undisturbed water it gets reflected. However , when we try to touch it the water becomes unstable and our reflection starts moving and further if we dip our hand the smooth surface gets destructed and reflection disappears.
