what will happen to the incident ray when it is incident to the point of contect of the mirror & upper layer of water

rockers753

the actual refltd ray will b below the ray which wld hav cum aftr rfltion had there been no water and wil be at an angle sineinvrseof(cos'i'/mew) to the surface of water inside it
whre 'i' is d angle of incidence and mew is d refractive index of water

pragna

angle of incidence would be greater than the angle of reflection.

i think rocker753 is about the magnitude of the ange of deviation but the actual reflected ray would be above the one that would have been had there been no water,as the light ray is entering from a rarer medium to a denser medium so it will shift towards the normal which is the surface layer.

this can also be proved by takin a differencial length on the refected ray and calculating the apparent depth over it. it will give you the equation of the actual light ray.

do rate me if you think im right.....

krishna.gopal

right answer by rocker ony that actual reflected ray will be above as pointed by pragna
