A convex mirror of radius of curvature 30 cm forms an image that is half the size of the object. The object distance is :
(2) -15 cm
f=+ R2=+15 cm; m=+ 12
a convex mirror forms a virtual, erect image of a real object.
m= ff-u 12= 1515-u
15-u=30 u=-15 cm
Answer: (2)
A biconvex lens of refractive index 1.5 has a focal length of 20 cm in air. Its focal length when immersed in a liquid of refractive index 1.6 will be:
If the distance between object and its two times magnified virtual image produced by a curved mirror is 15 cm, the focal length of the mirror must be:
If the refractive index of the material of a prism is ( A2 ), where A is the angle of prism then the angle of minimum deviation will be
Two immiscible liquids of refractive indices 85 and 32 respectively are put in a beaker as shown in the figure. The height of each column is 6 cm. A coin is placed at the bottom of the beaker. For near normal vision, the apparent depth of the coin is 4 cm. The value of is . [figure]
