Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.

Question

1. Laser light of wavelength 500.0 nm illuminates two identical slits, producing an
interference pattern on a screen 90.0 cm from the slits. The bright bands are 1.00 cm
apart, and the third bright bands on either side of the central maximum are missing in
the pattern. Find the width and the separation of the two slits.
2. Parallel rays of green mercury light with a wavelength of 546 nm pass through a slit
covering a lens with a focal length of 60.0 cm. In the focal plane of the lens, the distance
from the central maximum to the first minimum is 8.65 mm. what is the width of the
slit?

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)
