A ray of light is incident on the surface of separation of a medium at an angle \[45{}^\circ \] and is refracted in the medium at an angle \[30{}^\circ \]. What will be the velocity of light in the medium [AFMC 1998; MH CET (Med.) 1999]

• A. \[1.96\times {{10}^{8}}\] m/s                                           
• B. \[2.12\times {{10}^{8}}\] \[m/s\]
• C. \[3.18\times {{10}^{8}}\]\[m/s\]                                     
• D. \[3.33\times {{18}^{8}}\]\[m/s\]
