Answer: The amplitude is 15 cm and wavelength is 150 cm.
Explanation:
The wavelength is the distance between two consecutive compression.
The amplitude is the maximum displacement of the wave.
According to the figure,
This wave is longitudinal wave.
So, The amplitude is 15 cm approximate.
Now, the wave length will be
The wavelength is the distance between two consecutive compression is
[tex]\lambda=d_{2}-d_{1}[/tex]
[tex]\lambda= 150-0[/tex]
[tex]\lambda=150\ cm[/tex]
Hence, The amplitude is 15 cm and wavelength is 150 cm.
