An object which is 5.0cm high is placed 15.0cm left of a convex lens with a focal length of 10.cm. A second lens which is placed 48cm to the right of the first lens and has focal length of 10cm. Determine the location of the final image, the magnification of the final image, and the height of the final image.

In Newton's ring experiment,the diameter of 10th ring changes from 1.40cm to 1.27cm when a liquid is introduced between the lens and the plate.to calculate the refractive index of the liquid.

Mass m slides without friction inside a hemispherical bowl of radius R. Show that if a particle starts from rest with a small displacement from equilibrium, it moves at simple harmonic motion with an angular frequency equal to that of a simple pendulum of length R. That is ω = √g/R.

How is the diffraction of X-rays by crystals??
