1.

Refractive index of diamond is 2. Speed of ligh in it is ...... Cm//s.

Answer»

`6xx10^(10)`
`3.0 XX 10^(10)`
`2 xx 10^(10)`
`1.5 xx 10^(10)`

Solution :`mu =("Speed of LIGHT c")/("Speed in MEDIUM v")`
`THEREFORE 2.0 =(3xx10^(10))/(v)`
`therefore v=3/2xx10^(10)`
`therefore v=1.5xx10^(10)" "cm//s`
