Answer:
The correct answer to the following question will be "4.08 × 10⁻¹⁹ Joule".
Explanation:
Given:
Wavelength, λ = 486.0 nm
As we know,
[tex]E=h\upsilon =\frac{hc}{\lambda}[/tex]
On putting the estimated values, we get
⇒ [tex]=\frac{1241.5 \ ev\ nm}{486 \ nm}[/tex]
⇒ [tex]=2.554 \ ev[/tex]
∴ 1 ev = 1.6 × 10⁻¹⁹ J
Now,
Energy, [tex]E=2.554\times 1.6\times 10^{-19}[/tex]
⇒ [tex]=4.08\times 10^{-19} Joule[/tex]
