Question

the de- broglie wavelenght of the electron is 600nm the velocity of the electron is
a) 1.8 x 10^3 m/s b) 1.2 x10^5 m/s
c) 5.4 x 10^3 m/s d) 1.2 x 10^3 m/s

Answer 1

Explanation:

here is ur answer..............

Answer 2

Answer:

c)1.2*10∧-5

Explanation:

WAVELENGTH (λ) = 600nm

According to De-Broglie Equation,

λ = h/mv

∴600 = 6.626*10∧-34/9.1*10∧-31*v        (h=6.626*10∧-34)(m=9.1*10∧-31)

∴ v =0.0012*10∧-3

v =1.2*10∧-5m/s
