On a day when the speed of sound in air is 340. m/s, a bat emits a shriek whose echo reaches it later. How far away was the object that reflected back the sound?
 
  What will be an ideal response?

Question 2

Both the microscope and the telescope make the object appear much larger. Why are these two instruments designed differently (e.g., why are the equations for magnification quite different)?

Answer to Question 1

4.25 m

Answer to Question 2

The object for a telescope is at infinity whereas the object of a microscope is very close to the objective. The ray diagrams and the designs are thus quite different.
