State True or false: If a man standing on a platform $2$ metres above the surface of a lake observes a cloud and its reflection in the lake
Solution:
We draw a figure according to the question, after observation we find that the height $( h)$ of the cloud from the surface is much more than the depth of the reflection of clouds in the lake.
$\Rightarrow h>d$ [$h=$height of the of the cloud and $d=$ depth of the lake]
So, the values of $\theta_1>\theta_2$ [$\theta_1=$ angle of elevation and $\theta_2=$ angle of depression]
Hence, the given statement is not true.
