An astronomical telescope has an angular magnification of 40 times. If the diameter of the objective is 12 cm and the length of the tube is 1m, calculate the focal length of the objective and the diameter of the exit pupil.

Given that the moon has about has the same angular size as the new 20 peso coin, held at 1m from the eye and that the diameter of the moon is 3.5 x 10^6 m estimate the distance from the earth to the moon.

A graded index fiber with a parabolic index profile supports the propagation of

742 guided modes. The fiber has a numerical aperture in air of 0.3 and a core diameter

of 70 μm. Determine the wavelength of the light propagating in the fiber.

Further estimate the maximum diameter of the fiber which gives single-mode

operation at the same wavelength.
