The critical angle for light going from medium A into medium B is $$\theta$$. The speed of light in the medium A is $$\mathrm{V}_{\mathrm{A}}$$. What is the speed of light in the medium $$\mathrm{B}$$ ?
- A$$\mathrm{V}_{\mathrm{A}} \sin \theta$$
- B$$\mathrm{V}_{\mathrm{A}} \tan \theta$$
- C$$\frac{\mathrm{V}_{\mathrm{A}}}{\tan \theta}$$
- D$$\frac{\mathrm{V}_{\mathrm{A}}}{\sin \theta}$$
