Write de-Broglie formula for the wavelength of matter waves.
What are matter waves? Explain. Write the formula for de Broglie wavelength. Write the name of the experiment which shows the dual nature of particles.
A proton and an \( \alpha \)-particle are accelerated by the same potential difference. Find out the ratio of their de Broglie wavelengths.
Draw a graph between de Broglie wavelength (\(\lambda\)) and momentum (\(p\)) of a moving particle. A proton and an \(\alpha\)-particle are accelerated by the same potential. Compute the ratio of their de Broglie wavelengths.
Electrons and protons are accelerated by the same potential difference. The ratio of their de Broglie wavelengths is:
Write equation of energy of photon in terms of Planck's constant (h) and wavelength (\(\lambda\)).
Write the de Broglie wavelengths in terms of kinetic energy.
If wavelength \( \lambda \) represents wave property and momentum \( p \) represents the particle property, then what will the expressions \( \lambda = \frac{h}{p} \) and \( p = \frac{h}{\lambda} \) represent?
