A ray of sunlight is passing from diamond into glass. The angle of incidence is 37.60o. The indices of refraction for the blue and red components of the ray are: blue: (ndiamond = 2.444, nglass = 1.531) and red: (ndiamond =2.410, nglass =1.520). Find the size of angle between the refracted blue and red ray in the glass.
In a popular amusement park ride, a rotating cylinder of radius3.00 m is set in rotation at anangular speed of 6.00 rad/s, as inFigure P7.51. The floor then drops away, leaving the riders suspended against the wall in a vertical position. What min..
