The dimensional formula is defined as the expression of the physical quantity in terms of its basic unit with proper dimensions. Dimensional formula of wavelength M 0 L 1 T 0 Dimensional formula of frequency M 0 LM 0 L. The Frequency is expressed in Hertz Hz.
M 1 L 0 T 0 M a L ab T -2ac a 1 a b 0 2a c 0.
F M L T-2 Its because the unit of Force is Netwon or kgms 2. F M L T-2 Its because the unit of Force is Netwon or kgms 2. Dimensional formula of wavelength M 0 L 1 T 0 Dimensional formula of frequency M 0 LM 0 L. Further we have the length of the wire.
