The dimensional formula for relative refractive index is


ANSWER

$$[M^0L^0T^0]$$


SOLUTION
Relative refractive index $$ { \mu  }_{ r }$$is a ratio of refractive index of medium $$ \mu $$ to refractive index of vacuum $$ { \mu  }_{ o }$$.
Hence dimensionless $$\mu_r=\dfrac {\mu}{\mu_0}=[M^0L^0T^0]$$
