This Instrument places an illuminated object of known size at a known distance p from the cornea, which then reflects some light from the object, forming an Image of it. The magnification M of the Image is measured by using a small vlewing telescope that allows a comparison of the Image formed by the cornea with a second callbrated Image projected Into the field of view by a prism arrangement. Determine the radius of curvature of the cornea when ?-35.0 cm and M-0.0 130 Need Help?

At an intersection of hospital hallways, a convex spherical mirror is mounted high on a wall to help people avoid collisions. The magnitude of the mirror's radius of curvature is 0.574 m. a) Locate the image of a patient 11.4 m from the mirror. (Use the correct sign conventions.) 0.02799 ?? Apply the mirror equation using the correct focal length and object distance to find the image distance. cm (from the mirror) (b) Indicate whether the image is upright or inverted. upright O inverted

Explanation / Answer

Problem 6)

Given,

focal length = -R/2 = - 0.574 / 2 = - 0.287 m

Using lens formula,

v = (u x f) / ( u - f ) = (11.4 * -0.287)/(11.4 - 0.287) = - 0.295 cm

Image will be upright
