Question

Sun Rays makes an angle 45° with the vertical at upper tip of pole fixed vertically on the surface of the earth and its length is 4 metre .the distance travelled by the light ray from the tip of the pole to the earth surface is

Answer 1

Answer:

4 metres is the answer for your question

Answer 2

Given is the angle sun rays make with the vertical at the tip of a long vertical pole, Find the distance traveled by the rays from the tip to surface.

Explanation:

• Let the tip of the pole be denoted by 'P', The foot of the pole be denoted by 'F', and the point on the surface be denoted by 'G'.
• Let the distance traveled by sun rays from the tip of the pole to the surface be denoted by 'd', $PG='d'\ m$
• Since the pole is vertical to the surface, the triangle PFG is a right-angled triangle at point F.  
• Now in triangle PGF the angle G is equal to the angle made by the sun rays with the vertical at point P, $\angle G=45$
• Hence from triangle PGF we get,
• $sin(G)=\frac{PF}{PG} \\ ->sin(45)=\frac{4}{d} \\->d=4\sqrt{2}\ m$    
• The distance traveled by the sun rays is $4\sqrt{2} \ m$.
