The lens in a Newton’s rings experiment has diameter 20 mm and radius of curvature R = 5.0 m. For l = 589 nm in air, how many bright rings are produced with the setup (a) in air and (b) immersed in water (n = 1.33)?

In the double-slit arrangement of Figure P37.21, d = 0.150 mm, L = 140 cm, A = 643 nm, and y = 1.80 cm. (a) What is the path difference d for the rays from the two slits arriving at P? (b) Express this path difference in terms of A. (c) Does P correspond to a maximum, a minimum, or an intermediate condition? Give evi- dence for your answer. Viewing screen

A slit of width d is placed in front of a lens of focal length 0.5 m and is illuminated normally with light of wavelength 5.89 × 107 m. The first diffraction minima on either side of the central diffraction maximum are separated by 2 × 10-³ m. The width d of the slit is m.

A spy satellite is in orbit a distance of 1.91 x 106 m above the earth's surface. It carries a telescope that can resolve two trees that are 1.34 m apart using light of wavelength 592 nm. What must be the minimum diameter of the telescope's lens (in meters)?

A plano-convex lens with radius of curvature R = 3.2 m is in contact with a flat plate of glass. A light source and the observer's eye are both close to the normal, as shown in the figure below. The radius of the 51st bright Newton's ring is found to be 9.4 mm. What is the wavelength of the light produced by the source? nm 2//1 Need Help? Read It 8:36 PM 4/11/2021

A research ship in the Pacific Ocean is testing a new method of detecting pollutants in ocean water (nwater=1.3330). Their experimental apparatus includes two lasers which hang over the side of the ship and point downward into the water (the lasers themselves are suspended in the air above the surface of the ocean). One laser is violet (λ=400 nm, αH2O = 0.0044 m-1) and the other is red (λ=700 nm, αH2O = 0.6 m-1). Both lasers are very bright, with an intensity of 3600 W/m2. What is the fraction of light coming from the red laser beam that is transmitted from the air into the water?   Incorrect. Tries 1/99 Previous Tries What is the intensity of the blue laser beam at a depth of 5.5 m?   Incorrect. Tries 1/99 Previous Tries What is the intensity of the red laser beam at a depth of 5.5 m?

EX. (1): Compute the NA, acceptance angle, and the critical angle of an optical fiber from the following data. n₁ (core) = 1.55 and n2 (cladding) = 1.50. Ans.: NA = 2 2 n₁₂² -n₂² F2 (15) 2 0.300.

A vehicle with headlights separated by 2.00 m approaches an observer holding an infrared detector sensitive to radiation of wavelength 885 nm. What aperture diameter is required in the detector if the two headlights are to be resolved at a distance of 10.0 km?

A multi-mode fiber optic has a core index of n = 1.492 and a cladding index of 1.489. The diameter of the core is 30.0 microns. Monochromatic light is focused into one end of a perfectly straight fiber which is 25.0 km long. What will be the difference in arrival time at the far end of the fiber for the axial and marginal rays?
