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.
Sound waves with frequency 3000 Hz and speed 343 m/s diffract through the rectangular opening of a speaker cabinet and into a large auditorium of length d = 100 m.The opening, which has a horizontal width of 30.0 cm, faces a wall 100 m away. Along that wall, how far from the central axis will a listener be at the first diffraction minimum and thus have difficulty hearing the sound? (Neglect reflections.)
Sound waves with frequency 4000 Hz and speed 350 m/s diffract through the rectangular opening of a speaker cabinet and into a large auditorium of length 100 m. The opening, which has a horizontal width of 31.0 cm, faces a wall 100 m away. Along that wall, how far from the central axis will a listener be at the first diffraction minimum and thus have difficulty hearing the sound?
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.
A glass sheet 1.10 μm thick is suspended in air. In reflected light, there are gaps in the visible spectrum at 573 nm and 645.00 nm. Calculate the minimum value of the index of refraction ?n of the glass sheet that produces this effect. ?=
assume that two waves of light in air, of wavelength 400 nm, are initially in phase. One travels through a glass layer of index of refraction n1 = 1.60 and thickness L. The other travels through an equally thick plastic layer of index of refraction n2 = 1.50. (a) What is the smallest value L should have if the waves are to end up with a phase difference of 5.65 rad? (b) If the waves arrive at some common point with the same amplitude, is their interference fully constructive, fully destructive, intermediate but closer to fully constructive, or intermediate but closer to fully destructive?
