Question

let me know the answer with explantion please

Answer 1

Answer:

The path of light will be visible through mixture of ink and water as it is a colloid and colloids scatter light ( tyndall effect)

Answer 2

Answer:

The path of light becomes visible in the mixture of ink and water.        

Explanation:

In beaker A the mixture formed by Copper sulphate and water is a Solution.

In beaker B the mixture formed by Ink and water is a Colloid.

In a solution the path of light is not visible because the particles of a solution are smaller than 1 nm (10 raised to -9 metre) in diameter.So, they do not scatter a beam of light. so, the path of light is not visible. This scattering of a beam of light is called Tyndall effect.

While in a colloid the path of light is visible because the particles of a colloid are big enough to scatter a beam of light. So, the path of light is visible.
