Water is transaparent;glass is transperent;when water falls on glass why we cant see?
The light still comes through because both water and glass are transluscent, but there’s two reasons why seeing clearly is difficult.
1) Light travels through water and glass at different speeds, and so get bent when it transitions between them.
2) If the water hits the window and sticks like a droplet, it acts like a lense or a sort of prism and also bends the light.
The more the light gets bent, the more distorted the image gets, and the harder it becomes to make sense of it, i.e to “see clearly.”

You can still see, but it will be distorted, as light will be bent by the phase change between liquid and “solid” (glass is actually a liquid, but a very viscous one).

You can’t see either easily because light passes through them, which is why they are transparent. If they were translucent, they would absorb light and you would not be able to see clearly through them. When an object is solid, it reflects light, it is opaque and cannot be seen through at all.

I think you typed “cant see” in place of “can see”. well, both are transparent, NOT INVISIBLE!! Definitely you can see anything thats a liquid or solid, bcoz of bending of light, as it enters from thin air into it, and back. You see the boundaries& mass encompassed between boundaries. It makes a visible image, your mind due to its past learning identifies it to be a liquid being puored on a solid. ITS SIMPLE!!
