Answer 2

Proof:

Note: Refer the image attached for pictorial reference.

As per the let us assume that P is the point which is at H meters distance from the lake,

The cloud point is C and the reflection point of the cloud is C`

Let us also assume that the distance of the cloud from the lake is X meters,

So we can say

As ,

Hence

So in

……… (i)

The same way for

……………. (ii)

So from (i) and (ii) we can say,

Hence proved that the height of the cloud
