Chapter 10: Q. 72 (page 645)

Reflecting Telescope - A reflecting telescope contains a mirror shaped like a paraboloid of revolution. If the mirror is 4 inches across at its opening and is 3 inches deep, where will the collected light be concentrated?

Short Answer

Expert verified

The collected light be concentrated at 0.33 inch .

Step by step solution

01

. Given information .

Consider the given distance and depth .

02

Step 2. Standard form of parabola used .

The standard form of parabola is x2=4aythe vertex of the parabola is at origin and the focus is on y parallel axis .

03

Step 3. Find the distance .

To find the distance of collected light substitute the values in equation of parabola .

Here x=2,y=3

x2=4ay22=4a路3a=0路33inch

Therefore the collected light will be concentrated at 0路33inch.
