Questions asked in this paper

Q1 Question No.1 is Compulsory
Q2 Attempt any three questions from the remaining questions Nos. 2 to 6 marks
Q4 Figures to the right indicate marks
Q1 Attempt any Five
- a) the divergence of vector function A= + 03
- b) What is antireflection coating? What should be the refractive index 03 minimum thickness of the coating?
- c) A glass material A with which an optical fibre is made has a refractive Index of 1.55.This material is clad with another material whose refractive index is 1.51. The light in the fibre is launched from air. Calculate the numerical aperture of the fibre
- d) What is the difference between Bottom up approach and Top down approach 03 with respect to nanotechnology?
- e) Write the difference between LED and Laser Diode. 03
- f) How is Lissajous figures used to measure unknown frequency? 03
- g) <A parallel beam of light of wavelength 5890 A is incident ona glass plate 03 having refractive index =1.5 such that the angle of refraction in the plate is the smallest thickness of the glass plate which will appear dark by reflected light
Q2 a) With the help of a proper diagram and necessary expression, explain how Newton’s ring experiment is useful to determine the radius of curvature of a plano convex lens. In a Newton ring’s experiment the diameter of dark ring is 0.336 cm and the diameter of 15" dark ring is 0.590cm.Find the radius of curvature of a plano convex lens, if the wavelength of light used is 5890A 8 marks
- b) monomode and multimode fibre? Explain the term V-number. 07 Calculate the number of step index optical fibre of diameter will transmit as its core and cladding refractive indices are 1.5 and 1.46 respectively. Wavelength of light used is 1.5 wm
- a). With a neat energy level diagram describe the construction and working of 08 He-Ne laser. What are its merits and demerits?
- b) What is diffraction grating and grating element? Explain the experimental 07 method to determine the wavelength of the spectral line using diffraction
- a) With a neat diagram explain the construction and working of scanning 05
- b) — Derive the Bethe law for electron refraction. 05
- c) Derive the condition for absent spectra in grating. 05
Q5 Draw the block diagram of an optical fibre communication system and explain the function of each block 5 marks
- c) An electron enters a uniform magnetic field B=0.23 X Wb/m? at 05 angle to B. Determine radius and the pitch of helical path. Assume electron speed to be 3 x 10’m/s
Q6 a) Find V.A at point OS
- b) A Newton’s rings set up is used with a source emitting two wavelengths A;= 05 6000A and A2 = 4500A. It is found that dark ring due to 6000A coincides with (n +2)" dark ring due to 4500A. If the radius of curvature of the lens is 90 cm, find the diameter of dark ring for 6000A
- c) Differentiate between stimulated and spontaneous emission. 05
