Chapter 26, Problem 52GP
|| A wildlife photographer uses a moderate telephoto lens of focal length 135 mm and maximum aperture f/4.00 to photograph a bear that is 11.5 m away. Assume the wavelength is 550 nm. (a) What is the width of the smallest feature on the bear that this lens can resolve if it is opened to its maximum aperture? (b) If, to gain depth of field, the photographer stops the lens down to f/22.0, what would be the width of the smallest resolvable feature on the bear?

1(a) In a Michelson interferometer is set for the white straight fringes. When a mica sheet ofthickness 0.005cm is put in front of the fixed mirror, then in order to bring back the coloredfringes to their original position, the movable mirror is moved by 0.0025cm. Calculate therefractive index of mica?
Once dark adapted, the pupil of your eye is approximately 7 mm in diameter. The headlights of an oncoming car are 120 cm apart. If the resolution of your eye is limited only by diffraction, at what distance are the two headlights marginally resolved? Assume the light’s wavelength in air is 600 nm andthe index of refraction inside the eye is 1.33. (Your eye is not really good enough to resolve headlights at this distance, due to aberrations in the lens.)
A spy satellite circles the Earth at an altitude of 180 km and carries out surveillance with a special high-resolution telescopic camera having a lens diameter of 35 cm. If the angular resolution of this camera is limited by diffraction, estimate the separation of two small objects on Earth's surface that are just resolved in yellow-green light (? = 550 nm).
