1)Suppose a certain laser can provide 80 TW of power in 1.2 nspulses at a wavelength of 0.29 µm. How much energy is contained injoules in a single pulse?
2)The maximum electric field 12 m from a point light source is 1.8V/m. What are (a) the maximum value of the magnetic field and (b)the average intensity of the light there? (c) What is the power ofthe source?
3)In Fig. 33-40, initially unpolarized light is sent into a systemof three polarizing sheets whose polarizing directions make anglesof ?1 = ?2 = ?3 = 62° with the direction of the y axis. Whatpercentage of the initial intensity is transmitted by the system?(Hint: Be careful with the angles.)
4)Figure 33-49 shows light reflecting from two perpendicularreflecting surfaces A and B. Find the angle (in o) between theincoming ray i and the outgoing ray r'.
5)In Fig. 33-57, a ray of light is perpendicular to the face ab ofa prism (n = 1.43). Find the largest value for the angle ? so thatthe ray is totally reflected at face ac if the prism is immersed(a) in air and (b) in water (n=1.33).
