When the object is placed very close to the lens, the image formed is virtual, erect and
Large number of thin strips of black paper are made on the surface of a convex lens of focal length 20 cm to catch the image of a white horse. The image will be
Match the positions of the object (Column A) with the corresponding positions of the image formed by a convex lens (Column B).

The lens formula is given by :
\[\frac{1}{f} = \frac{1}{v} - \frac{1}{u}\]

Consider the statements given below and choose the correct option :
Statement 1 : Angle of deviation produced by a prism depends on the angle of the prism.
Statement 2 : Dispersion takes place in a prism because the refractive index of the refracting medium is different for different wavelengths.
A light ray travels obliquely from a denser medium to a rarer medium. It will bend:
