3. In an experiment for determination of refractive index of glass of a prism by
(2016 Main)
(a) 1.5
(b) 1.6
(c) 1.7
(d) 1.8
Show Answer
Answer:
Correct Answer: 3. (a)
Solution:
Now, we know that
It we take the given deviation as the minimum deviation then,
The given deviation may or may not be the minimum deviation. Rather it will be less than this value. Therefore,
Hence, maximum possible value of refractive index is 1.51 .
