Define work function.

Define wave functions.

Define the photoelectric work function of a metal..

Define the term work function of a metal. The threshold frequency of a metal is 2f_0 is incident on the metal plate, the maximum velocity of electrons emitted is v_1 , when the frequency of the incident radiation is increased of 5f_0 the maximum velocity of electrons emitted is v_2 . Find the ratio of v_1 to v_2 .

The work function of metal A is higher than the work function of metal B. which of these metals has higher threshold wavelength?

State the relation between work function and threshold frequency.

Let R be the set of real numbers. Define a real function f : R rarr R by f (x) =x + 10 . Sketch the graph of this function.

Define functional group?
