"To use a graphical approach to determine whether there is a difference between the focal length of a lens when used with red and green light."(adsbygoogle = window.adsbygoogle || []).push({});

What would I expect to see?

What sort of results do you think I will get?

What would be the variable?

I need to use the equation 1/u + 1/v = 1/f can anyone help in explaining it?

Has anyone done anything similar before?

Thanks for any help.
