Last question!!!!!
330 m
990 m
0.5 m
Answer:
The wavelength of the sound wave traveling at 330 m/s is 0.5 m.
Explanation:
Given:
Speed of sound wave is,
Frequency of the sound wave is,
Speed of a sound wave is related to its frequency and wavelength as:
, where, is the wavelength.
Now, plug in 330 for , 660 for and solve for . This gives,
Therefore, the wavelength of the sound wave traveling at 330 m/s is 0.5 m.
