If the critical angle for total internal reflection from a medium to vacuum is $45°$, the velocity of light in the medium is:
1. $$1.5\times10^{8}$$ m/s
2. $$\frac{3}{\sqrt{2}}\times10^{8}$$ m/s
3. $$\sqrt{2}\times10^{8}$$ m/s
4. $$3\times10^{8}$$ m/s

1. tan-1 (0.750)
2. sin-1 (0.500)
3. sin-1 (0.750)
4. tan-1 (0.500)
