Answer:
Correct answer is Wave A has a greater pitch and frequency
Explanation:
To understand the given figure, we should know the definition of wavelength, frequency and pitch
Wavelength
wavelength is defined as distance between two successive wave crests or troughs.
Frequency
Frequency is defined as the number of waves which passes through a given point per second. SI unit of frequency is Hertz.
Pitch
our ear understand the frequency of a sound wave as pitch. A a lower frequency sound has a lower pitch and a higher frequency sound has a higher pitch.
In given figure Wave A has lower wavelength and higher frequency so it have higher pitch than wave B.
Mass = 1.2 kg = 1200 grams.
Volume = mass/density = 1200 cm3.
