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.
Q. Give the drawbacks of Sommerfeld’s atom model? Drawbacks of Sommerfeld's atom model: (i) It couldn't explain the distribution and arrangement of electrons in atoms.
Discuss the diffraction of light through n slits using plane transmission grating.
If two forces P & Q act at such an angle that the resultant force r=p. Then show that if P is doubled the new resultant is at right angle Q and it's value is ( 4P 2 -Q 2 ) 1/2
Vector Direction The significance of 'direction' could be seen in the dissimilarity among velocity and speed. In physics, speed is a pure scalar or something along with a magni
Kirchhoff's law of radiation (G.R. Kirchhoff): The emissivity of a body is equivalent to its absorptance at the simialr temperature. Kirchhoff's laws (G.R. Kirchhoff)
A hydrogen atom is in the ground state. It absorbs energy and makes a transition to the n = 3excited state. The atom returns to the ground state by emitting two photons. What are
