Question

If the boy looks through the tube with 4 mirrors fixed at 45 degrees. How far the ball will appear from the boy?

• A.
  F - (A + E)
• B.
  F
• C. A + B + C + D + E
• D. 2F

Answer 1

The correct option is C A + B + C + D + E

As you can see that the plain mirrors have been placed at 45 degrees in the tube. Hence, the distance between the ball and the boy would be summation of the gaps in between i.e.

Apparant distance between the boy and the ball = (A + B + C + D + E) units
