Write down de Broglie's relation and explain the terms therein.

State Heisenberg's Uncertainty principle.

What is the effect of intensity of light and potential on photoelectric current?

Describe an experiment to study the effect of frequency of incident radiation on stopping potential.

Summarise the photon picture of electromagnetic radiation.

What is the de Broglie wavelength of a ball of mass $0.12 \mathrm{kg}$ moving with a speed of $20 \mathrm{m}/\mathrm{s}$? What can we infer from this result? (Planck's constant $h=6.62\times {10}^{-34} \mathrm{J}·\mathrm{s}$ )

How did Einstein's photoelectric equation account for the effect of frequency of incident light on stopping potential?

Describe the Davisson and Germer experiment. What did this experiment conclusively prove?
