Relation of time and frequency.

Frequncy is directly proportional to time.

From Planck's law E=hf ... eq(1) Since, P=W/t And W=E So, P=E/t or          E=Pt ... eq(2) Put the value of E from eq (2) in eq (1) Pt=hf or          f=Pt/h or          f=(P/h)(t) Suppose that constant power is supplied then f=(constant)t Hence, f is directly proportional to t.
