Focal length equation lens
WebMay 4, 2005 · Hey all, I recently did an experiment using a diverging or convex lens, to produce different images according to the focal point. For the experiment I found the focal length, and set up the lens and light source at that distance. I used just paper for a screen to produce the real images created. WebJan 15, 2024 · In fact, the power of a lens is, by definition, the reciprocal of the focal length of the lens: P = 1 f In that the SI unit of focal length is the meter (m), the unit of optical power is clearly the reciprocal meter which you can write as 1 m or m − 1 in accord with your personal preferences. This unit has been assigned a name.
