Solved Problems
1. Calculate the wavelength associated with an electron with energy 2000 eV.
(Set-1–Sept. 2006), (Set-1–May 2004), (Set-1–May 2003), (Set-4–Nov. 2003)
Sol: E = 2000 eV = 2000 × 1.6 × 10–19 J
2. Calculate the velocity and kinetic energy of an electron of wavelength 1.66 × 10 –10 m.
(Set-1, Set-3–May 2006), (Set-2, Set-3–June 2005), (Set-2–May 2004), (Set-4–May 2003)
Sol: Wavelength of an electron (λ) = 1.66 × 10–10 m
To calculate KE:
3. An electron is bound in one-dimensional infinite well of width 1 × 10 ...
