A ray of light of wavelength 540 nm traveling in air is incident
on a slab of transparent material. The refractive index of the
material is 1.47. Calculate the wavelength of light in the
material.

A gun barrel of mass 600 kg has a recoil spring of stiffness 294 kN/meter. If the barrel recoils 1.3m on firing determine (i) the initial recoil velocity of the barrel (ii) the critical damping co-efficient of the dash pot which is engaged at the end of the recoil strike (iii) the equation of motion of the gun barrel if the time of recoils is of time period.

State energy method of finding the equation of motion of a system.

A diffraction grating has a spacing of 1.6 * 10^-6 meters. A beam of light is incident normally on the grating. The 1st order maximum makes an angle of 20 deg with the un-deviated beam. What is the wavelength of the incident light?
