Problem 7: Your camera’s zoom lens has an adjustable focal length ranging from 55 to 150 mm. Part (a) What is the maximum power of the lens, Pmax, in diopters? Numeric : A numeric value is expected and not an expression. Pmax = __________________________________________ Part (b) What is the minimum power of the lens, Pmin, in diopters? Numeric : A numeric value is expected and not an expression. Pmin = __________________________________________ Problem 8: A camera with a 50.0 mm focal length lens is being...
A typical human lens has an index of refraction of 1.430. The lens has a double convex shape, but its curvature can be varied by the ciliary muscles acting around its rim. At minimum power, the radius of the front of the lens is 10.0 mm, whereas that of the back is 6.00 mm. At maximum power, the radii are 6.50 mm and 5.50 mm, respectively. If the lens were in air, what would be the maximum power and associated...
A LENS has a focal length of 150 mm. A real object is 225 mm from the lens. What is the lateral magnification?
If the refractive power of this lens was DECREASED, would the focal length for the lens increase or decrease? Explain your answer. 2. If the refractive power of this lens was DECREASED, would the focal length for the lens increase or decrease? Explain your answer. (2 pts) Question 1 4 pts Answer BOTH parts of this question 1. If light passing through a convex lens reaches its focal point 12.5 cm from the lens, what is the refractive power of...
A typical human lens has an index of refraction of 1.41. The lens has a double convex shape, but its curvature can be varied by the ciliary muscles acting around its rim. At minimum power, the radius of the front of the lens is 10.0 cm, while that of the back is 6.00 mm. At maximum power the radii are 6.00 mm and 5.50 mm, respectively. (The numbers can vary somewhat.) If the lens were in air, (a) what would...
A telephoto lens with focal length of 120mm has f-numbers ranging from f/2.8 to f/22. What is the diameter of the lens aperture at f/2.8? What is the diameter of the lens aperture at f/22?
An f/2.80 CCD camera has a 105-mm focal length lens and can focus on objects from infinity to as near as 30.0 cm from the lens. (a) Determine the camera's aperture diameter. Deter- mine the (b) minimum and (c) maximum distances from the CCD sensor over which the lens must be able to travel during focusing. Note: "f/2.80" means "an f-number of 2.80."
The condenser lens of a slide projector has a focal length of 25 mm. It produces a twice magnified image of the lamp filament. How far should the projection lens be from the condenser? Ans.: 75 mm
A compound microscope has an objective lens of focal length 10.0 mm with an eyepiece of focal length 15.5 mm , and it produces its final image at infinity. The object to be viewed is placed 2.0 mm beyond the focal point of the objective lens. a. How far from the objective lens is the first image formed? b. What is the overall magnification of this microscope?
