Question

State the SI unit of wavelength and frequency.

Answer 1

Wavelength:

• It is the distance between similar points in the adjacent cycles of a waveform signal propagated in space or ahead of a wire.
• The formula of the wavelength as $\lambda =\frac{v}{f}$

Frequency:

• The number of waves that pass a fixed point in unit time.
• It also explains the number of cycles or vibrations face during one unit of time by a body in cyclic motion.

Hence, the SI unit of wavelength is a meter(m).

and the frequency is hertz(Hz).
