A transverse pulse of frequency 9 Hz traves 4.5m in 0.6 s. Calculate the wavelength of the pulse.

  • A 3.33 m
  • B 0.30 m
  • C 0.83 m
  • D 1.20 m

The correct answer is C. 0.83 m

Wavelength (\(\alpha\)) = \(\frac{Velocity (V)}{Frequency (f)}\)

Velocity = \(\frac{Distance}{Time}\) = \(\frac{4.5}{0.6}\)

= \(\frac{7.5}{9.0}\)

= 0.83m
