- $9\,\Omega$
- $11\,\Omega$
- $10\,\Omega$
- $9.9\,\Omega$
View Solution
2.
In determining the refractive index of a glass slab using a travelling microscope, the following readings are tabulated:
(a) Reading of travelling microscope for ink = 8.123 cm
(b) Reading of travelling microscope for ink through glass slab = 6.123 cm
(c) Reading of travelling microscope for chalk dust on glass slab = 8.123 cm
From the data, the refractive index of a glass slab is:}
- 1.199
- 1.398
- 1.500
- 1.569

- Less
- Equal
- Zero
- More
View Solution
4.
