3. The speed of light in glass
is 2 x 10 km/s. What
is the refractive index of
glass?

Anis: 1.5

2. Light enters from air to
dense flint glass with
refractive index 1.65. What
will be the speed of
light in flint glass?

Ans: 1.81 x 10' ms​

Answer 1

Answer:

$\huge \underline \mathfrak{ \red{answer}}$

Ques 1 (Ans)➡Refractive index of glass =

Speed of light in speed

speed of light in vaccum.

$= \frac{3 \times {10}^{8}m/s }{2 \times {10}^{5} km/s} = \frac{3 \times {10}^{8} m/s}{2 \times {10}^{8} m/s} \\ = 1.5$

ques 2(ans) ➡ The speed of light in the air is 3x10 power 8m/s. This includes speed of light vaccum and refracted in the glass.
