Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.

Question

2 If light leaves a material of refractive index 1.45 and crosses an
abrupt boundary into a material of refractive index 1.0, the Fresnel
loss would be:
(a) 0.346 dB
(b) 0.149 dB
(c) 1.613 dB
(d) 3 dB
3 Absorption loss is caused by:
(a) insufficient stirring of the ingredients during manufacture
(b) changes in the density of the fiber due to uneven rates of cooling
(c) microscopic cracks in thẻ cladding which allow leakage of the vacuum
in the core
(d) impurities in the fiber
4 Rayleigh scatter is most severe:
(a) in light with a short wavelength
(b) in blue light on the Earth and black light on the moon
(c) in low frequency light
(d) at sunset
5 Bending losses:
(a) always result in breakage of the fiber
(b) can be caused by microbends and macrobends
(c) are used to detect the length of fiber on a drum
(d) are caused by the difference in the operating temperature of the core
compared with the cladding on active fibers

When unpolarized light passes through a diffraction grating, does it become polarized? (a) No, it does not. (b) Yes, it does, with the transmission axis parallel to the slits or grooves in the grating. (c) Yes, it does, with the transmission axis perpendicular to the slits or grooves in the grating. (d) It possibly does because an electric field above some threshold is blocked out by the grating if' the field is perpendicular to the slits.

Show that the distribution of intensity in a double-slit pattern is given by Equation 36.9. Begin by assuming that the total magnitude of the electric field at point P on the screen in Figure 36.4 is the superposition of two waves, with electric field magnitudes E1=E0sintE2=E0sin(t+) The phase angle in in E2 is due to the extra path length traveled by the lower beam in Figure 36.4. Recall from Equation 33.27 that the intensity of light is proportional to the square of the amplitude of the electric field. In addition, the apparent intensity of the pattern is the time-averaged intensity of the electromagnetic wave. You will need to evaluate the integral of the square of the sine function over one period. Refer to Figure 32.5 for an easy way to perform this evaluation. You will also need the trigonometric identity sinA+sinB=2sin(A+B2)cos(AB2)
