Light rays emerge from denser medium (n_2), refract from curved surface and then travel through rarer medium (n_1), formula for this is ….........

Answer»

`-(n_2)/(U)+(n_1)/(V)=(n_1-n_2)/(R)`
`-(n_2)/(u)+(n_1)/(v)=(n_2-n_1)/(R)`
`-(n_1)/(u)+(n_2)/(v)=(n_2-n_1)/(R)`
`-(n_1)/(u)+(n_2)/(v)=(n_1-n_2)/(R)`

SOLUTION :`-(n_2)/(u)+(n_1)/(v)=(n_1-n_2)/(R)`
