but I'm solving for focal length... for another example the number on the intercepts was 0.14
would that be the focal length or would I actually have to solve 1/.14 which comes out to like 7.0 something... or would the focal length be just 0.14
Is this confusing? I think I'm confusing myself
I understand completely how to go about doing this problem... I know that you would have to plot the points and draw a line of best fit and that the x-intercepts and y-intercepts would equal 1/f... but what would the actual focal length be? and how do you calculate the gradient? This is actually...
