Question

When yo stand in a swimming pool and look at your feet, your legs appear to be bent. Which is the term for this phenomenon

Answer 1

Answer:

RERFACTION

Explanation:

Yes this happen and this is because of phenomena known as refraction.

Refraction is an phenomena in which light waves deflect from their original direction of propagation after passing through other medium of different refractive index.

Or we can also say that, it is the bending of light when its passes through medium of different refractive index.

Now, in this situation as the person is looking towards his legs from the air downwards , so here the light entering in his eyes passes through two mediums which are water and air.

So as he see his upper body which is above water and light through it only passes through one medium and no bending occurs and everything seems to be normal but, as he looks his legs light passing through his legs to his eyes passes through two different medium and bending of that light occur and our legs seems to be bend with respect to our upper body and all this is due to refraction.  

Answer 2

Refraction - the fact or phenomenon of light, radio waves, etc., being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density.
