Answer:

The unit of refractive power is
m^(-1)

Step-by-step explanation:

We know that lens power is also know as refractive power.The power of lens is the inverse of its focus length but focus length should be in meter. Refractive power is also known as optical power.


Refractive\ power=(1)/(f)\ m^(-1)

So the unit of refractive power is
m^(-1)

Watts : Watts is the unit of power.It is the rate of work done per second.

Joules : Joules is the unit of energy.
