Question 159: Ray Optics

Question

As shown in the figure, after passing through the medium 1 . The speed of light $$v_{2}$$ in medium 2 will be :
$$\left(ight.$$ Given $$\mathrm{c}=3 	imes 10^{8} \mathrm{~ms}^{-1}$$ )

Accepted Answer

$$V = {1 \over {\sqrt {\mu \varepsilon } }} = {1 \over {\sqrt {{\mu _r}{\varepsilon _r}{\mu _0}{\varepsilon _0}} }}$$
$$ \Rightarrow {V_2} = {c \over {\sqrt 9 }} = {10^8}$$ m/s

Answer

$$1.0 	imes 10^{8} \mathrm{~ms}^{-1}$$

Answer

$$0.5 	imes 10^{8} \mathrm{~ms}^{-1}$$

Answer

$$1.5 	imes 10^{8} \mathrm{~ms}^{-1}$$

Answer

$$3.0 	imes 10^{8} \mathrm{~ms}^{-1}$$
