Explain the term 'work function' of a metal. The threshold frequency of a metal is f0. When the light of frequency 2f0 is incident on the metal plate, the maximum velocity of electrons emitted is v1. When the frequency of the incident radiation is enhanced to 5f0, the maximum velocity of electrons emitted is v2. Find the ratio of v1 to v2.
(1) Holes works as virtual charge, although there is no charge on holes. (2) Effectual volume of hole is more than electron. (3) Mobility of hole is fewer than electron.
what is the equation for work
how would the results change if the angle of the third load in second experiment increased ? state the differences
When current is passed by a junction of two dissimilar solids, the temperature is either evolved or absorbed at the node. This effect is known as Peltier effect
how the direction of friction is obtained?
the magnitude and direction of acceleration of body both are constant will the body moves in straight line
Explain about the transmission electron microscope. The Transmission Electron Microscope Transmission electron microscopy (TEM) is a microscopy method; a beam of electrons i
Voltage division: In a series circuit Ohm's law applies for each component. However, since the current is common to all components we have: V1 = IR1, V2 = IR2,
Energy that is radiated or transmitted in the form of rays or waves or particles.
At high reverse voltage, due to high electric field, the minorities charge carriers, while crossing the junction acquires very high velocities. A chain reaction is prepared, giving
