11.Dual Nature of Radiation and matter
medium
A $100\,watt$ light source is emitting radiations of wavelength $5000\,\mathop A\limits^o $. The rate of emission of photons is of the order of
A
$10^{40}$
B
$10^{20}$
C
$10^{10}$
D
$10^{5}$
Solution
Power $=\,nhv\,=\frac {nhc}{\lambda }$
Where $n$ is the number of photons per second.
