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.
CPH has mass and velocity. What is its De Broglie wavelength? Answer; since I told before, the wavelength of CPH is equal of electromagnetic wavelength when it is growing.
Quantum Theory of Light: Wave theory failed to describe some new effects in 19th century. A German Physicist Max Plank gave theory about the nature of light. 1. Light is emi
