Question

Now change the Environment to "Glass", and the Object to "Air." You should see something like: The normal lines again indicate a radial direction back to the center of curvature. But the outgoing rays are diverging. If you trace the outgoing rays back to a point where they would converge, that would be the location of the focal point for this lens. Identify your variables, n_1, n_2, R_1, and R_2, and calculate the focal length of this lens using the lensmaker equation. m = ____ n_2 = ____ R_1 = ____ R_2 = ____

Explanation / Answer

Solution:

Use these equations:

1/f =  (-1)(1/R1 - 1/R2)

because (air) = 1

and hence, use the lens maker's formula:
i.e;

1/f = 1/v - 1/u

{just take care of the signs carefully}

in the given case ;

R2 by using the first equation but for that you need f(focal length)

just put these in the above 2 -equations.

u =

R1 = (Due to been a straight line)
