Rayleigh criterion; resolving power:
A criterion for finding out how finely a set of optics might be able to distinguish. It start with the supposition that central ring of one image must fall on the primary dark ring of the other; for an objective lens along with diameter d and employing light along with a wavelength lambda (usually taken 560 nm), the resolving power is approximately given trhough 1.22 lambda/d.
The fraction of vacancy sites in a metal is 1X10 -10 at 500 0 C. What will be the fraction of vacancy sites at double the temperature?
