LPN to BSN Bridge Program. Designed LPNs who want to obtain a Bachelor of Science in Nursing degree; typical program length: 3 to 4 years. A BSN degree is often a requirement for many positions as is the entry point for professional nursing practice.
More quantitatively, since the diverging lens is 28 cm to the right of the converging lens, the object distance is do = 28 cm + 12 cm = 40 cm; this is the distance between the diverging lens and the image formed by the converging lens.
The effect of dispersion on the focal length of a lens can be examined by calculating the change in the focal length with wavelength. The table below starts with a biconvex lens designed to have a focal length of 10.0 cm for violet light (400 nm) in crown glass.
