Chapter 25, Problem 61AP
An American standard analog television picture (non-HDTV), also known as NTSC, is composed of approximately 485 visible horizontal lines of varying light intensity. Assume your ability to resolve the lines is limited only by the Rayleigh criterion, the pupils of your eyes are 5.00 min in diameter, and the average

is the minimum separation of 2 small sources of red lights on Earth that you can resolve by eye when you are flying 3.0 km above the ground? Assume the light's wavelength in air is 633 nm, the index of refraction inside the eye is 1.333 and a pupil diameter of 4.00 mm.
Both sides of a uniform film that has index of refraction n and thickness d are in contact with air. For normal incidence of light, an intensity minimum is observed in the reflected light at λ2 and an intensity maximum is observedat λ1, where λ1> λ2. (a) Assuming no intensity minima are observed between λ1 and λ2, find an expression for the integer m in as shown in terms of the wavelengths λ1 and λ2. (b) Assuming n = 1.40, λ1 = 500 nm, and λ2 = 370 nm, determine the best estimate for the thickness of the film.
Fig. 1 shows two light rays of wavelength 610 nm traveling from air through twodifferent media with refractive indices n1 = 1.5 and n2 = 1.6 and to air again. Assumingthat the two waves are initially out of phase by 180° and they become exactly in phase once they pass through the two media, determine (a)the smallest possible value of L. (b)the second smallest possible value of L.
