Question

yes find out F1 and F2 of symmetric convex lens experimentally then which conclusion is true a )F1 is equals to F to B) F one is greater than F to C) F 1 is less than f2d) the F1 is not equal to F2​

Answer 1

Answer:

A) F1=F2

Step-by-step explanation:

a) F1=F2

As symmetric convex lens radius and equal focal lengths are also equal.

A telescope is the combination of two systems constituted by lens which makes them calibrated with the back focal point and the front focal point.

So, lets think that it is not symmetric. We would get to a contradiction, then the only conclusion is that they are equal.

Since it is a symmetric convex lens the focal length are equal, then 1 = 2.
