11.Dual Nature of Radiation and matter
easy
एक क्वान्टा की आवृत्ति ${10^{15}}Hz$ है एवं $h = 6.6 \times {10^{ - 34}}J{\rm{ - }}\sec $ जूल सैकण्ड है, तो ऊर्जा होगी
A
$6.6 \times {10^{ - 19}}J$
B
$6.6 \times {10^{ - 12}}J$
C
$6.6 \times {10^{ - 49}}J$
D
$6.6 \times {10^{ - 41}}J$
Solution
$E = h\nu = 6.6 \times {10^{ – 34}} \times {10^{15}} = 6.6 \times {10^{ – 19}}J$
