(B) False.Let the height of the cloud above the surface of the lake be $H$. The reflection of the cloud in the lake will be at a depth of $H$ below the surface of the lake.The man is standing at a height of $3 \ m$ above the surface of the lake. Let the observer's eye level be $O$.The angle of elevation $	heta_1$ of the cloud is given by $	an(	heta_1) = \frac{H - 3}{x}$,where $x$ is the horizontal distance from the man to the cloud.The angle of depression $	heta_2$ of the reflection is given by $	an(	heta_2) = \frac{H + 3}{x}$.Since $H - 3 
eq H + 3$,the angle of elevation $	heta_1$ is not equal to the angle of depression $	heta_2$.

'True' or 'False' and justify your answer.
If a man standing on a platform $3 \ m$ above the surface of a lake observes a cloud and its reflection in the lake,then the angle of elevation of the cloud is equal to the angle of depression of its reflection.
