1.	If change in energy \[(\Delta E)=3\times {{10}^{-8}}J,\,\,h=6.64\times {{10}^{-34}}J\text{-}s\] and \[c=3\times {{10}^{8}}\,m/s,\] then wavelength of the light is [CBSE PMT 2000]
A.	\[6.36\times {{10}^{3}}\text{{ }\!\!\mathrm{\AA}\!\!\text{ }}\]
B.	\[6.36\times {{10}^{5}}\text{{ }\!\!\mathrm{\AA}\!\!\text{ }}\]
C.	\[6.64\times {{10}^{-8}}\text{{ }\!\!\mathrm{\AA}\!\!\text{ }}\]
D.	\[6.36\times {{10}^{18}}\text{{ }\!\!\mathrm{\AA}\!\!\text{ }}\]
Answer» D. \[6.36\times {{10}^{18}}\text{{ }\!\!\mathrm{\AA}\!\!\text{ }}\]

If change in energy \[(\Delta E)=3\times {{10}^{-8}}J,\,\,h=6.64\times {{10}^{-34}}J\text{-}s\] and \[c=3\times {{10}^{8}}\,m/s,\] then wavelength of the light is [CBSE PMT 2000]
