a - R1 positive
b - R2 negative
c - R1 = 2*R2 ---> -R2 = R1/2 ---> R2 = - R1/ 2
>>>>>>>>>>>> R1 = 13.35 cm
d - f(new) = 6.5 cm
e- f(medium) = 28.93 cm
Problem 2 [20 points) For the parts of the below question, fill in the empty boxes with your answer (YOUR ANSWER MUST BE ONLY A NUMBER; DO NOT WRITE UNITS; DO NOT WRITE LETTERS). A thin biconvex lens made of heavy flint glass (n = 1.89) has a focal length in air of 5 cm. The radius of curvature of the first surface i twice the second surface's radius. C 0 C R2 the radius of the first surface? a) [3 points) What is the sign Choose one: Opositive Onegative b) [3 points) What is the sign of the radius of the second surface? Choose one: positive Onegative c) (5 points) Calculate the radius of curvature of the first surface Ri. R1 = ст d) (5 points) If R1 = 17.36 cm, R2 = 8.678 cm, n = 1.89, calculate the new focal length in air of this lens, fnew- fnew = Jcm e) (4 points) If the lens is now immersed in a medium that has an index of refraction of 1.575, calculate the focal length in the medium fmedium (use R1 = 17. 36 cm, R2 = 8.678 cm and n = 1.89). fmedium= ст
