Question 1
Calculate the wavelength (in nanometer) associated with a proton moving at 1.0 × 103 ms–1 (mass of proton = 1.67 × 10–27 kg and h = 6.63 × 10–34 Js)
Question 2
Two particles A and B are in motion and wavelength of A is 5 × 10-8 m. The wavelength of B, so that its momentum is double that of A, will be
Question 3
What is the value of de-broglie wavelength of electron accelerated at 400V?
Question 4
An electron diffraction experiment was performed with a beam of electrons accelerated by a potential difference of 10.0 KV. What is the wavelength of electron beam. (1 KV = 1000 eV for electrons).
Question 5
