How do we know that when a ray of light is incident on still water it will get reflected or refracted.

Solution

When light ray fall on Stull water, every time some part of light always gets refracted and rest gets reflected.
We cant tell to how much extend but both these phenomena do occur.

We know that shiny, well polished surfaces like mirror reflect light well. We can also see our reflection in still water because it acts like a mirror. So if I make a laser light or any torch light fall on still water, will it reflect light? Plz explain the answer

Q. When a light ray is incident at polarising angle on the surface
1) Reflected ray is completely polarised
2) Refracted ray is partially polarised
3) Intensity of refracted ray is less than incident ray

Q. When light is incident on a glass block at polarizing angle
