Question

is air around us is always transparent
​

Answer 1

Answer:

No

Explanation

Because air contains so few atoms, light waves run into very few of them when they shine through air. So the air looks transparent. If you put enough dust in the air, the particles of dust absorb the light and the air stops being transparent.

Answer 2

Answer:

air around us is transparent due to which we can see the object like trees , building etc.

But when the thick smoke, cloud , dust is present in the air does it not remain transparent because dust ,smoke etc absorbs the light.

For Example:- during sandstorm we cannot see the things due to dust present in the air.
