GO Figure 17-39 shows two point sources S 1 and S 2 that emit sound of wavelength λ = 2.00 m. The emissions are isotropic and in phase, and the separation between the sources is d = 16.0 m. At any point P on the x axis, the wave from S 1 and the wave from S 2 interfere. When P is very far away ( x ∞), what are (a) the phase difference between the arriving waves from S 1 and S 2 and (b) the type of interference they produce? Now move point P along the x axis toward S 1 . (c) Does the phase difference between the waves increase or decrease? At what distance x do the waves have a phase difference of (d) 0.50 λ , (e) 1.00 λ , and (f) 1.50 λ ? Figure 17-39 Problem 23.

Imagine you are out for a stroll on a sunny day when you encounter a lake. Unpolarized light from the sun is reflected off the lake into your eyes. However, you notice when you put on your vertically polarized sunglasses, the light reflected off the lake no longer reaches your eyes. What is the angle between the unpolarized light and the surface of the water, in degrees, measured from the horizontal? You may assume the index of refraction of air is nair=1 and the index of refraction of water is nwater=1.33 . Round your answer to three significant figures. Just enter the number, nothing else.
