Question

चांदी का कार्य फलन 5.26*10^-19 जूल है इसकी देहलीतरंग धैर्य ज्ञात करो (h = 6.6*10^-34 जूल/से) ? ​

Answer 1

solution-

देहली तरंग धैर्य $\lambda$= ?

कार्यफलन w = 5.26*10^-19

$\omega \: = h \nu_{0} \\ \\ \boxed{ \omega \: = h \: \frac{c}{ \lambda} } \: \: \: \: \: \: \: \: \: \: \: \: \: \left\{ \: \because \nu_{0} = \frac{c}{ \lambda _{0} } \right \}$

$5.26 \times {10}^{ - 19} = \frac{6.6 \times {10}^{ - 34} \times 3 \times {10}^{8} }{ \lambda} \\ \\ \lambda = \frac{6.6 \times {10}^{ - 34} \times 3 \times {10}^{8} }{5.26 \times {10}^{ - 19} } \\ \\ \lambda = 3.764 \times {10}^{ - 7} m \\ \lambda \: = 3.764 \times {10}^{ - 7} \times {10}^{10} A {}^{0} \\ \\ \lambda \: = 3.764 \times {10}^{3} {A}^{0} \\ \\ \lambda \: = 3764 {A}^{0}$
