A bulb is emitted electromagnetic radiation of $$660 \mathrm{~nm}$$ wavelength. The total energy of radiation is $$3 \times 10^{-18} \mathrm{~J}$$. Th...

Assertion : The chemical properties of different isotope are same. Reason : Isotopes having same number of neutron.

The work function of a metal is $$4.2 \mathrm{~eV}$$. If radiation of 2000 $$\mathop A\limits^o$$ fall on the metal then the kinetic energy of the fas...
