Answer:

The index of refraction for the piece of glass is 1.52

Explanation:

Given that,

Speed of light in vacuum, c=2.99\times 10^8\ m/s

Speed of light through a piece of glass is, v=1.97\times 10^8\ m/s

The ratio of speed of light in vacuum to the speed of light in a medium is called refractive index i.e.

n=\dfrac{c}{v}

n=\dfrac{2.99\times 10^8}{1.97\times 10^8}

n = 1.52

Hence, the index of refraction for the piece of glass is 1.52

Option (b) is correct.The index of refraction for the glass is 1.52

Explanation:

velocity of light in vacuum= C= 2.99 x 10⁸m/s

Velocity of light in glass = V= 1.97 x 10⁸m/s

The refractive index is given by n=\frac{c}{v}

n= 2.99 x 10⁸/1.97 x 10⁸m/s

n= 1.52

Thus the refractive index of glass is 1.52

The incorrect statement about electromagnetic waves is C. induction of electric fields by changing magnetic fields only occurs if a conducting material is present.
Electromagnetic waves do not rely on any medium for propagation, which means that the generation of fields is irrespective of the presence of a conducting material.

Answer:

n_cladding = 1.4764

Explanation:

We are told that θ_max = 5 °

Thus;

θ_max + θ_c = 90°

θ_c = 90° - θ_max

θ_c = 90° - 5°

θ_c = 85°

Now, critical angle is given by;

θ_c = sin^(-1) (n_cladding/n_core)

sin θ_c = (n_cladding/n_core)

n_cladding = (n_core) × sin θ_c

Plugging in the relevant values, we have;

n_cladding = 1.482 × sin 85

n_cladding = 1.4764
