Question

Calculate the wavelength of a wave if its frequency is 256 Hz and and speed of the wave is 350 m/s.

• A. 89,600 m
• B. 350 m
• C. 94 m
• D. 1.4 m
• E. 0.73 m

Answer 1

Answer: (D)

1.4 m

Given : $\nu =256$ Hz $v=350$ m/s

Thus wavelength of the wave $\lambda =\frac{v}{\nu }=\frac{350}{256}\approx 1.4$ m
