- Cell size and magnification
- cm --> mm = x10
- mm --> um = x1000
- um --> nm = x1000
- mm --> um = x1000
- um = micrometres. nm = nanometre
- Resolution for the human eye = 100um.
- Actual size = Image size/ magnification
- Image size = Actual size x magnification
- Magnification = Image size/ actual size
- Total magnification = Eye piece lens magnification x objective lens
- Eyepiece=x15 objective=x12 Magnification = 15x12= 180 = x180
- Image size = 50mm, magnification = x1200 A = I/M = 50/1200 = 0.0416 x 1000 = 41.6um
- Leave calculations for actual size in um and calculations for image size in mm
- cm --> mm = x10
