Mass defect in a fusion reaction of Hydrogen to Helium is $0.02866\text{u}$. The energy liberated per nucleon is approximately: (Given $1\text{u}=931\text{MeV}$)

For photoelectric emission, the cutoff frequency is $\nu$. If radiation of frequency $2\nu$ impinges on the plate, the maximum velocity of emitted electrons is:

The wavelength ${\lambda }_e$ of an electron and ${\lambda }_p$ of a photon of same energy $E$ are related by:

A plano-convex lens (${\mu }_1$) fits exactly into a plano-concave lens (${\mu }_2$). Their plane surfaces are parallel. Focal length of the combination is:

For a normal eye, the cornea provides power of $40\text{D}$ and the eye lens provides $20\text{D}$. The estimated distance between the retina and the lens is:
