SUMMARY

The discussion centers on the concept of optical power in lens equations, specifically addressing a focal length of 6.7 m-1. Optical power is defined as the reciprocal of the focal length (P = 1/f). Therefore, in the lens equation 1/p + 1/q = 1/f, the correct interpretation is that 1/p + 1/q equals 6.7, not 1/6.7. This confirms that the optical power directly influences the relationship between object distance (p), image distance (q), and focal length (f).

PREREQUISITES
  • Understanding of basic optics principles

Homework Statement


I am given a question with the focal length stated in optical power
i.e 6.7m-1

what is optical power it is stated that it is = to 1/f

so in the equation 1/p + 1/q = 1/f
is it right to assume that 1/p + 1/q = 6.7
or is it 1/6.7
??

Yes, optical power is defined as 1/f for the lens.
Your first assumption is correct.
1/p + 1/q = power of lens
