D. 359 nm

What Is The Wavelength Of Light With 553 X 1019 J Of Energy The Speed Of Light In A Vacuum Is 300 X 10 Ms And Plancks Constant Is 6626 1034 Js A 399 Nm B 278 Nm class=

Sagot :

Answer:

D. 359 nm

[tex]{ \boxed{ \bf{ energy = \frac{hc}{ \lambda} }}} [/tex]

lambda is the wavelength

c is the speed of light

h is the Planck's constant

[tex]{ \sf{5.53 \times {10}^{ - 19} = \frac{(6.626 \times {10}^{ - 34}) \times (3.00 \times { {10}^{8} }) }{ \lambda} }} \\ \\ { \sf{\lambda = 3.59 \times {10}^{ - 7} }} \\ { \sf{\lambda = 359 \: nm}}[/tex]
