Problems on De-Broglie Hypothesis
1. An electron is moving under a potential of 150 V. Calculate the wavelength of the electron waves?
2. What is the K.E of an electron whose de-Broglie wavelength is 5000 ˚A?
3. Find the energy of the neutron in units of electron volt whose de-Broglie wavelength is 1˚A?
4. An electron and proton are both accelerated through the same potential difference V. Compare their de Broglie wavelengths.
