11.Dual Nature of Radiation and matter
easy
The spectrum of radiation $1.0 \times {10^{14}}Hz$ is in the infrared region. The energy of one photon of this in joules will be
A
$6.62 \times {10^{ - 48}}$
B
$6.62 \times {10^{ - 20}}$
C
$\frac{{6.62}}{3} \times {10^{ - 28}}$
D
$3 \times 6.62 \times {10^{ - 28}}$
Solution
(b) $E = h\nu = 6.64 \times {10^{ – 34}} \times 1.0 \times {10^{14}}$$ = 6.62 \times {10^{ – 20}}J$
