List the various types of aberrations. What causes them and how can each be reduced?
A 7.5binocular produces an angular magnification of-7.50 , acting like a telescope. (Mirrors are used to make the image upright.) If the binoculars have objective lenses with a 75.0cm focal length, what is the focal length of the eyepiece lenses?
A student鈥檚 eyes, while reading the blackboard, have a power of 51.0 D. How far is the board from his eyes?
Unless otherwise stated, the lens-to-retina distance is 2.00 cm.
People who do very detailed work close up, such as jewellers, often can see objects clearly at much closer distance than the normal 25 cm.
(a) What is the power of the eyes of a woman who can see an object clearly at a distance of only 8.00 cm?
(b) What is the size of an image of an 1.00 mm object, such as lettering inside a ring, held at this distance?
(c) What would the size of the image be if the object were held at the normal 25.0 cm distance?
If the lens of a person鈥檚 eye is removed because of cataracts (as has been done since ancient times), why would you expect a spectacle lens of about \({\rm{16 D}}\) to be prescribed?
