Hi All!

Im a bit confused regarding the relationship between focal length and the thickness of a lense. In the lab that we performed, my data seems to be skewed and I am unable to decipher the trend. Can someone explainwhat happens to the focal length as the thickness of the lenses descreases? does it decrease or increase? .. im thinking it decrease. kindly let me know and please provide a brief explanation. thank you!

Hi itryphysics! :smile:

It depends, mostly, on the radius of curvature rather than the thickness … see http://en.wikipedia.org/wiki/Focal_length :wink:
