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.
Contact forces: types of forces that result when the two interacting objects are apparent to be physically linking each other. Ex: frictional forces, tensional forces, normal f
When a metal is illuminated with radiation with a wavelength of 152 nm, photoelectrons are ejected with a velocity of 7.9 x 10 5 m/s. What is the work function, in eV, of th

(i) Meter : The presently accepted definition of meter is the length of path travelled by light in space in 1/299,792,458th second. (ii) Kilogram : Kilogram is the fundamental
Explain the formation of newton ring
It's working is based on the detail that if a beam of electron is subjected to the crossed electric field and magnetic field , it experiences a force because of each field. In ca
Lenz's law (H.F. Lenz; 1835): An induced electric current always pass in such direction that it opposes the change generating it.
