Asked by kelvin calin

A wave has a wavelength of 4.9 m and a velocity of 9.8 m/s. The medium through which this wave is traveling is then heated so that the velocity is doubled.

If the frequency remains constant, what is the wavelength of the heated wave?

2.5 m
9.8 m
14.7 m
19.6 m

Wavelength doubles because f = v/λ is constant. Initial f = 9.8/4.9 = 2.0 Hz. With v = 19.6 m/s, λ = v/f = 19.6/2.0 = 9.8 m.
