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 wa

ve passes through a cloud of nitrous oxide, its wavelength changes to 16 m, while its frequency remains the same. What is its new speed? (The equation for the speed of a wave is v= f x 1.)
A. 350 m/s
B. 16 m/s
C. 5,600 m/s
D. 256 m/s​

Answer:

D. 256 m/s

Explanation:

f = Frequency of the wave = 16\ \text{Hz}

\lambda = Wavelength = 16\ \text{m}

Speed of a wave is given by

v=f\lambda

\Rightarrow v=16\times 16

\Rightarrow v=256\ \text{m/s}

The speed of the wave as it passes through the cloud of nitrous oxide is 256\ \text{m/s}.

You hear a sound in the distance. Suddenly the sound gets deeper, decreasing in pitch. Which can you assume about the sound wave
oksian1 [2.3K]

Answer:

A. The wavelengths of the new sound waves are longer

Explanation:

This is the Doppler effect which can be best illustraded  for the case of a siren of an ambulance approaching us having a greater frequency and getting lower in frequency and deeper as the ambulance passes  us.

Since the wavelength is inversely proportional to the frequency it follows the wavelengths are longer when the frequency decreases lowering its pitch and getting deeper.
