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.
Water at 10 Celsius flows at uniform velocity of 0.1 m/sec into a parallel plate channel, which is wide in the third direction. The parallel plates are at 20 Celsius and are 1.0 cm

How do we experimentally know that MOSEFT device is working?
When an electron makes transition from higher energy level having energy E2(n2) to a lower energy level having energy E1 (n1) then a photon of frequency v is emitted.
