April 2, 2009 PHY 2054 Discussion Spring ‘09 Conceptual Review: Chapter 22 A . Nature of Light 1. If you double the wavelength of a monochromatic light, by what factor does the energy content of individual photon change? 2. Express the minimum angular frequency in Fizeau’s experiment in terms of speed of light, # of teeth N and distance d . 1. Two mirrors meet at a right angle. A beam of light strikes one of the mirrors at an angle of 20º from the normal. What is the angle of reflection after it is reflected from both mirrors. 2. A monochromatic light is incident on an air-water interface. Compare the velocity, frequency and wavelength in air and those in water. 4. A beam of light both reflects and refracts at the air-glass surface. What is angle of incidence that would result in the reflected and refracted rays being perpendicular to each other? C. Dispersion 1. Does the index of refraction increase/decrease with increasing frequency? 2. The index of refraction for red light in water is 1.331 and that for blue light is 1.340. If a ray of white
