Answer 2

$<b>Hello Friend<b>$ ❤️❤️

The answer of u r question..✌️✌️

Given,

Energy of each quantum=1ev

E=hc/ (lamda)

lamda=hc/E

$\frac{66. {3}^{ - 34} \times 3 \times {10}^{8} }{1.6 \times {10}^{ - 19} \times {10}^{ - 9} }$


$\frac{198}{16} \times {10}^{2}$
=12.3×10^3

$= 1.23 \times {10}^{3}$

Thank you..⭐️⭐️
