Question

if we focused the light ray through the solution can we see the light beam in it

Answer 1

Hi friend,

They will discover how this fact leads to the existence of shadows. Students will explore the way an object’s size, shape, position, and orientation determines the shadow it creates and how it is affected by a particular light source. They will identify an object’s shadow as the region from which a light source is not visible because the object obstructs the line of sight.
They will also find that we “see” the world by collecting light that enters our eyes. This means that if no light enters our eyes from a particular direction we perceive that direction as dark. This is less obvious than it seems. For example, in the classroom, once the lights are turned on there is usually no area that appears dark because the room is filled with reflecting objects — the walls and everything else — so that light is impinging on our eyes from all directions. In the emptiness of space, light (from the Sun) may be present but, with the absence of objects to reflect it to our eyes, we see darkness.


Hope this helps you...
Please mark it as brainliest answer....

Answer 2

The scattering of light by colloidal particles is known as Tyndall effect.
So, if a solution is true solution then it does not scatter a beam of light passing through it but a colloidal solution[ as particles are big enough ] scatters a beam of light passing through it and renders its path visible.
In other words, a true  solution does not show Tyndall effect but a colloidal solution shows Tyndall effect.
