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 focal length f is positive for converging lenses, and negative for diverging lenses. The reciprocal of the focal length, 1/f, is the optical power of the lens. If the focal length is in metres, this gives the optical power in dioptres (inverse metres). Lenses have the same focal length when light travels from the back to the front as when light goes from the front to the back.
