Question

solve it...........​

Answer 1

Ⓗⓞⓛⓐ

E = 500eV

= 500 × 1.6 × 10^-19 j

= 8 × 10^-17 j

h = 6.6 × 10 ^-34 js

m = 9.11 × 10^-31 kg

now, lemda = h / √ 2mE

= 6.6 × 10 ^-34/ √ 2× 9.11 × 10^-31 × 8 ×10^-17

= 6.6 × 10 ^-34 / 12.07 × 10^-24

= 5.5 × 10^-11m

= 0.55 A°

Answer 2

hola

E = 500eV

E = 500eV= 500 × 1.6 × 10^-19 j

E = 500eV= 500 × 1.6 × 10^-19 j= 8 × 10^-17 j

E = 500eV= 500 × 1.6 × 10^-19 j= 8 × 10^-17 jh = 6.6 × 10 ^-34 js

E = 500eV= 500 × 1.6 × 10^-19 j= 8 × 10^-17 jh = 6.6 × 10 ^-34 js m = 9.11 × 10^-31 kg

E = 500eV= 500 × 1.6 × 10^-19 j= 8 × 10^-17 jh = 6.6 × 10 ^-34 js m = 9.11 × 10^-31 kg now, lemda = h / √ 2mE

E = 500eV= 500 × 1.6 × 10^-19 j= 8 × 10^-17 jh = 6.6 × 10 ^-34 js m = 9.11 × 10^-31 kg now, lemda = h / √ 2mE = 6.6 × 10 ^-34/ √ 2× 9.11 × 10^-31 × 8 ×10^-17

E = 500eV= 500 × 1.6 × 10^-19 j= 8 × 10^-17 jh = 6.6 × 10 ^-34 js m = 9.11 × 10^-31 kg now, lemda = h / √ 2mE = 6.6 × 10 ^-34/ √ 2× 9.11 × 10^-31 × 8 ×10^-17 = 6.6 × 10 ^-34 / 12.07 × 10^-24

= 5.5 × 10^-11m

= 5.5 × 10^-11m = 0.55 A°
