A sound wave traveling through dry air has a frequency of 16 hz, a
wavelength of 22 m, and a speed of 350 m/s. when the sound wave passes
through a cloud of methane, its wavelength changes to 28 m, while its
frequency remains the same. what is its new speed? (the equation for the
speed of a wave is v= f * 1.)

Answer:

[tex]\huge\boxed{\sf v = 448\ m/s}[/tex]

Explanation:

Given data:

Frequency = f = 16 Hz

Wavelength = λ = 28 m

Required:

Speed = v = ?

Formula:

v = fλ

Solution:

Put the givens.

v = (16)(28)

v = 448 m/s
