Show that the superposition of two linearly polarized light waves having different amplitude and a finite phase difference can be used to produce elliptically plane polarized light waves.

A diverging lens of -30 cm focal length produced an image which is 1/3 the height of the object. What would be the distance of the image?

2. What will be the change in frienge pattern in young double slit experiment even if either or the slits are emerged in a liquid of refracting indices β

What will be the change in frienge pattern in young double slit experiment even if two micafoils having same refracting indecs and thickness L1 and L2 (L1>L2) are placed in the path of interfaring raise

A particle of mass M is released from rest on a rough inclined plane, which makes an
angle of 30° with the horizontal. It is observed that the particle moves a distance of 3 m
in 3 s. What is the particle’s acceleration? Draw a properly labelled free body diagram.
Calculate the coefficient of kinetic friction between the particle and the surface of the
inclined plane.
