A plano-convex glass lens of radius of curvature 3 m rests on an optically flat glass plate. The arrangement is illuminated from above with monochromatic light of 569-nm wavelength. The indexes of refraction of the lens and plate are 1.6. Determine the radii of the first and second bright fringes in the reflected light. First bright fringe: m [5 points] 2 attempt(s) made (maximum allowed for credit = 5) [after that, multiply credit by 0.5 up to 10 attempts]...

Chapter 35, Problem 37. The radius of curvature of the convex surface of a planoconvex lens is 68.4 cm. The lens is placed convex side down on a perfectly flat glass plate that is illuminated from above with red light having a wavelength of 580 nm. Find the diameter of the second bright ring in the interference pattern. Can you also please explain why you used the formulas in each step.

A very fine wire 7.65×10?3 mm in diameter is placed between two flat glass plates. Light whose wavelength in air is 660 nm falls (and is viewed) perpendicular to the plates and a series of bright and dark bands is seen. Part A How far apart are the dark fringes if the glass plates are each 21.5 cm long? Express your answer to three significant figures and include the appropriate units. ?x =____ (units?)
