In a spectrometer experiment three prisms A, B, C with same angle of prism but of different materials of refractive indices μ A = 1.33 , μ B = 1.55 and μ C = 1.44 are used. The corresponding angles of minimum deviation D A , D B , D C measured will be such that
  • a)
    DA > DB > DC
  • b)
    DA < DB < DC
  • c)
    DA < DC < DB
  • d)
    DB > DA > DC
Correct answer is option 'C'. Can you explain this answer?

Explanation:

Principle of Minimum Deviation:
- According to the principle of minimum deviation, for a given angle of prism, the angle of minimum deviation is different for different materials of the prism.
- The angle of minimum deviation is the angle at which a ray passing through the prism emerges without deviation.

Relation between Refractive Index and Minimum Deviation:
- The refractive index of a material is directly proportional to the angle of minimum deviation. This means that a material with a higher refractive index will have a larger angle of minimum deviation.

Given Refractive Indices:
- μA = 1.33, μB = 1.55, μC = 1.44
- From the given refractive indices, we can conclude that the material with the highest refractive index is B, followed by C and then A.

Order of Angles of Minimum Deviation:
- Since the angle of minimum deviation is directly proportional to the refractive index, the order of angles of minimum deviation will be in the opposite order of refractive indices.
- Therefore, the correct order of angles of minimum deviation will be:
- DA < dc="" />< />

Conclusion:
- The correct relationship between the angles of minimum deviation measured for prisms A, B, and C will be DA < dc="" />< db.="" this="" is="" because="" the="" refractive="" index="" is="" directly="" proportional="" to="" the="" angle="" of="" minimum="" deviation,="" and="" the="" prism="" with="" the="" highest="" refractive="" index="" will="" have="" the="" largest="" angle="" of="" minimum="" deviation.="" db.="" this="" is="" because="" the="" refractive="" index="" is="" directly="" proportional="" to="" the="" angle="" of="" minimum="" deviation,="" and="" the="" prism="" with="" the="" highest="" refractive="" index="" will="" have="" the="" largest="" angle="" of="" minimum="" />
