(i) It has of continuously varying wavelengths in a exact wavelength range.
(ii) It is given by solids, liquids and highly compressed gases heated to high temperature.
(iii) E.g. Light from the sun, candle flame, filament of incandescent bulb etc.
Q. The work function of a metal surface is 1.8 eV. Compute the threshold wavelength. Work function W = hγ o = h C / λ 0 λ 0 = h C / W = 6.626 X 10 -34 X 3 X 10 8
A wheel is mounted on a stationary axle starts at rest and is given the following angular acceleration a =(9-12t) (SI units)where t is the time after the wheel begins to rotate.Fin
