It having of a Cu plate coated with a thin layer of cuprous oxide (Cu2O). On this plate is laid a semi transparent thin film of silver.
When light fall, the electrons emitted from the layer of Cu2O and move towards the silver layer. Then the silver layer changes into negatively charged and copper plate become positively charged. A potential dissimilarity is set up among these two and current is set up in the external resistance.
a) Heat produced or absorbed at a junction is proportional to the current by the junction. b) This effect is produced when current is passed by junction of suitable materials.
Stefan-Boltzmann law (Stefan, L. Boltzmann): The radiated power P (it is rate of emission of electromagnetic energy) of hot body is proportional to the radiating surface area,
a beam of electron is incident on barrier 6eV high and 0.2 nm wide. find the energy in eV these should have if 1% of them are to get through the barrier.
Regard as an electron and a proton at an instant in time to be at a separation of 5 cm from each other. Presume the pair to be totally isolated from its surroundings in the vacuum
