Mirror Formula and Magnification An object of ... QuestionAn object of size 7 cm is placed at 27 cm in front of a concave mirror of focal length 18 cm. At what distance from the mirror should a screen be placed, so that a sharp focused image can be obtained ? Find the size and th...
Magnification, m=1n So, 1n=−vu or v=−un By using mirror formula, 1f=1v+1u =1−u/n+1u ⇒u=−(n−1)f Was this answer helpful? 96Similar Questions Q1 A convex mirror of focal length f forms an image which is 1n times the object. The distance of the object from the...

convex mirror, concave mirror and flat mirror. The mirror formula is, 1f=1v+1u where, f is the focal length v is the image distance from the pole of mirror u is the object distance from the pole of mirror The formula for magnification of a mirror is...
Solution ocal length, f= ? Object distance, u=-25 cm Magnification, 1.4=-v/ -25 v= 35 cm Using the mirror formula, 1/v + 1/u=1/f 1/35-1/25 =1/f f = - 62.5 cm Suggest Corrections 0
In spite of the long history of using conic mirrors for these purposes, the maximum magnification of the three primary types of conic mirror (hemisphere, hemiellipsoid, and dual paraboloid) had not been compared quantitatively. To our knowledge, an exact magnification formula has not been ...
angle in radians subtended by the distant object at the lens. This formula provides a means for defining focal length and for measuring the focal length of an unknown lens. The thin lens In a thin lens such as aspectacle, the two principal planes coincide within the lens, and then the...
