Question : The ratio of the length of a rod and its shadow is $1: \sqrt{3}$. The angle of elevation of the sun is:
Option 1: $90^{\circ}$
Option 2: $30^{\circ}$
Option 3: $45^{\circ}$
Option 4: $60^{\circ}$
Correct Answer: $30^{\circ}$
Solution : The ratio of the length of a rod and its shadow, $\frac{AB}{BC} = \frac{1}{\sqrt{3}}$ ⇒ $\tan \theta = \frac{AB}{BC}$ ⇒ $\tan \theta = \frac{1}{\sqrt{3}}$ ⇒ $\tan\theta = \tan 30^{\circ}$ ⇒ $\theta =30^{\circ}$ Hence, the correct answer is $30^{\circ}$.
