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.
As s1 is decreased, s2 must be increased. For example, consider a normal lens for a 35 mm camera with a focal length of f = 50 mm. To focus a distant object (s1 â â), the rear nodal point of the lens must be located a distance s2 = 50 mm from the image plane. To focus an object 1 m away (s1 = 1,000 mm), the lens must be moved 2.6 mm farther away from the image plane, to s2 = 52.6 mm.
