Question

1. A Nd: YAG laser (1.106 micrometer) beam travels through a glass flint window of refractive index of 1.98. Determine: (a) the speed, the wavelength, the frequency, and the period of the laser beam inside the glass; (b) the energy of its photon outside the glass in Joules.

2. Light travels from a block of glass with an index of refraction of 1.41 into air. (a) if the angle of reflection is 32 degrees, what is the angle of incidence? (b) what is the angle of refraction? (c) draw a diagram.

3. Calculate the radiant flux density emitted by an object (emissivity=0.72) at room temperature (69.8 degrees) is this a blackbody or a graybody? Explain
