Question

If the velocity of the electron in electron microscope is measured as 1.6x10m/s,
calculate de Broglie wavelength in pm associated with this electron.​

Answer 1

Answer:

From de Broglie’s equation,

λ = h/mv

Substituting the values in this equation,we get

6.626x 10-34 / (9.11x10-31)(1.6x106)

= 4.55 x 10-10m

= 455pm
