(a) What is the minimum angular spread of a 633-nm wavelength He-Ne laser beam that is originally 1.00 mm in diameter? (b) If this laser is aimed at a mountain cliff 15.0 km away, how big will the illuminated spot be? (c) How big a spot would be illuminated on the moon, neglecting atmospheric effects? (This might be done to hit a corner reflector to measure the round-trip time and, hence, distance.)

How to rized rigu o ast 15s/AUT. MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. The spacing of ruled lines on a diffraction grating is 1830 mm.

4. A Fabry-Perot etalon has a peak transmission at 500 nm corresponding to an order m=3, and a spectral width of 1 nm for light at normal incidence. Suppose the etalon is rotate%3; does the peak transmission shift to the red or blue? In addition to a calculation, explain why in qualitative terms (with a sketch if needed). By how far would you have to rotate the etalon to shift the transmission peak by 1.5 nm? Assume the refractive index inside the etalon is 1.6.

Compute the radiative flux transferred from a 2.5 m2 polished aluminum plate at 1000 K to a camera that has a 2 inches optical aperture (objective diameter) and a silicon CMOS focal plane array (about 1 cm2), located 10 m away from the plate. Assume that the plate is a Lambertian radiator and all light entering the camera aperture reaches the detector array. Use Figure 1 as a guide for your calculations. Assume that the lens is completely transparent at all wavelengths, the sensor filter is a bandpass filter that completely blocks all small wavelengths up to UV and long wavelengths beyond 1 THz. In the passing band the filter is perfectly transparent. The emissivity of polished aluminum and transmittance of the atmosphere can be considered constant over the entire spectrum (search for the approximate values online – cite the used reference).
You used a 632nm laser to diffract images onto a wall 2 meters away using two separate diffraction gratings; one with 100 lines per mm and the other 300 line per mm. Is there a theoretical limit to the number of orders observable with your diffraction gratings? If not, explain why. If so, determine the limits for your grating.

please reexplain this paragraph two-beam interference with the double exciter:the circular waves generated by the double exciter are super- posed at the points where they meet. The areas with no wave motion indicate cancellation (minima).the minima and maxima are positioned along hyperbolas with the excitation centers as focal points. the relationships given in the section h0rinciples” for the positions of the hyperbolas are confirmed experimentally.The interference patterns are determined by the distance be- tween exciters, and by the wavelength. the number of hyperbo- las increases with the exciter spacing and the wavelength, and the hyperbolas open further.
