Fizeau (see figure below), the distance between light source and mirror was 11.48 km and the wheel had 720 notches. The experimentally determined value of c was 2.995 x 105 m/s when the outgoing light passed through one notch and then returned through the next notch. Calculate the minimum angular speed of the wheel for this experiment. (Enter your answer to four significant figures.) rad/s Toothed Mirror wheel Need Help? Read it Master It Submit Answer 2.

ASK YOUR TEACHER PRACTICE ANOTHER The figure below shows a laser beam (1) incident on a block of acrylic glass, with an angle of incidence of 54.09, The beam partially reflects from the surface (2) and partially transmits (3) a refracted beam into the material, with a refraction angle of 32.90. The transmitted beam itself reflects off the bottom surface (4) and refracts again when it exits the material (5). The laser beam's wavelength is 632.8 nm.

ASK YOUR TEACHER PRACTICE ANOTHER A ray of monochromatic light is incident on the face of a prism in the shape of an equilateral triangle (that is, the apex angle of the prism is 60.0). The incidence angle of the light ray is 71.0. The prism is made of a transparent material with an index of refraction of 1.457 (at the light ray's wavelength). (a) Calculate the angle of refraction at the first surface (in degrees). (Round your answer to at least one decimal place.) (b) Calculate the angle of incidence at the second surface (in degrees). (Round your answer to at least one decimal place.) (c) Calculate the angle of refraction at the second surface (in degrees). (Round your answer to at least one decimal place.) (d) Calculate the angle between the incident and emerging rays (in degrees). (Round your answer to at least one decimal place.) Need Help? Read It
