Light of wavelength 600 nm is incident normally on a diffraction grating. Two adjacent maxima occur at angles given by sin u =0.2 and sin u = 0.3.The fourth-order maxima are missing. (a) What is the separation between adjacent slits? (b) What is the smallest slit width this grating can have? For that slit width, what are the (c) largest, (d) second largest, and (e) third largest values of the order number mof the maxima produced by the grating?

Measuring distance with high precision is a critical goal in engineering. Numerous devices exist to perform such measurements, with many involving laser light. Shining light through a double slit can be used to measure distance if (1) both the wavelength of the light beam and the distance between slits are known and (2) the spacing between the minima and maxima appearing on the screen can be measured. But this method requires a physical measurement of distance on the object, which may not be practical. To create a laser-based measurement device that does not require placing a physical ruler on the object, a Nd:YAG laser is mounted inside a box so that the beam of the laser passes through two slits rigidly attached to the laser. Although 1064 nm is the principal wavelength of a Nd:YAG laser, the laser can be switched to numerous secondary wavelengths, including 1052 nm, 1075 nm, 1113 nm, and 1319 nm.

In an interference experiment using a monochromatic source emitting light of wavelength λ=600 nm, the fringes are produced by two long, narrow slits separated by a distance 'd' mm. The fringes are formed on a screen which is situated at a distance 7 m from the slits. Determine 'd', if the fringe width w==6 mm.

Light of wavelength 616 nm is incident normally on a diffraction grating. Two adjacent maxima occur at angles given by sin 0 = 0.26 and sin 0 = 0.37. The fourth-order maxima are missing. (a) What is the separation between adjacent slits? (b) What is the smallest slit width this grating can have? For that slit width, what are the (c) largest, (d) second largest, and (e) third largest values of the order number m of the maxima produced by the grating?

There is a circular slit with its radius a = 0.1mm. The distance between the slit plane and detector plane is given by R=1m. Roughly estimate the requirement of the wavelength of incident light for Fraunhofer diffraction with appropriate justification.
