Question

Calculate the Wavelength associated with electrons moving in velocity of 10% of velocity of light ​

Answer 1

Answer:

0.2432 * 10⁻¹⁰ m

Explanation:

λ =h / mv

mass of electrons = 9.1 * 10⁻³¹ Kg

velocity = 3* 10⁸ * 10/100

             = 3* 10⁷ m/s

λ = 6.64 * 10⁻³⁴ / ( 9.1 * 10⁻³¹ ) ( 3* 10⁷)

  = 0.2432 * 10⁻¹⁰ m
