Question

A student learns that the sound travels in a waveform. The image shows the sound waves produced by a man and a woman. What can be concluded from the image? (a) closer the waves, greater will be the amplitude (b) closer the waves, greater will be the frequency (c) farther the waves, greater will be the amplitude (d) farther the waves, greater will be the frequency

Answer 1

Sound travels in a waveform so the correct answer is closer the waves, the greater will be the frequency            

Explanation:

• A sound wave is a simple pressure wave created by the movement of air molecules away from the source, and it has a frequency and amplitude, just like all waves. It's also related to wavelength.
• As previously stated, it is a pressure wave, and the surrounding molecules are forced to shift back and forth from their equilibrium position.
• The frequency and amplitude of the sound wave are determined by the movement of the molecules. These characteristics give the sound wave its distinct pitch and volume.
• A person with normal hearing can detect noises in the 20-20,000 Hertz range.
• From the given image it is clear that man shouts in low pitch, so the frequency is low and woman shouts in high pitch, the frequency is high.
• The wavelength and frequency of a wave are inversely related. This indicates that high-frequency waves have a short wavelength, while low-frequency waves have a greater wavelength. The closer the waves are together, the higher the frequency.
