Could you please help me here to get the F. E. (Semester - I I) Examination Engineering Physics issued by Savitribai Phule Pune University?

I will get the F. E. (Semester - I I) Examination Engineering Physics issued by Savitribai Phule Pune University so that you can prepare hard for it.

Here is the exam paper

Q.1 a) Explain the formation Newton’s ring with diagram and drive [06] the diameter of bright ring.

b) Discuss the use of ultrasonics for flaw Detection [03]

c) A auditorium of volume 5500m3 is found to have reverberation [03]
time 2.5 secs. The sound absorbing surface of the auditorium has an area of 750m2. Calculate the average absorption coefficient of the auditorium.

OR

Q.2 a) Define magnetostriction effect. Explain how magnetostriction [06 ]
oscillator is used to produce ultrasonic waves with the help of neat circuit diagram.

b) Explain with diagram how interference Principle is used to design [03] anti reflection caoting.

c) Monochromatic light from He-Ne laser source (λ=6328A0) is incident [03] normally on a diffraction grating having 6000lines/cm. Find the angle at which one would observe second order maximum.

Q.3a) Define Double refraction. Explain Huygen’s Theory of Double [06]
refracting crystal with diagram.
b) Define Fermi level. Plot the variation of Fermi level with the [03]increase of temperature for n-type and p-type semiconductor.
