Question

from which source (sound) 1 is created by reputable equipment. the diagram shows the sound wave by source of the sound
which statement correctly classifies the waves produced in the equipment, assuming all of the waves are traveling at the same speed?

• sound wave 2 is made by a tone of lower frequency and twice the amplitude of sound wave 1.
• sound wave 1 is made by a tone of the same frequency and four times the amplitude of sound wave 3.
• sound wave 1 is made by a tone of the same frequency and the same amplitude as sound wave 2
• sound wave 3 is made by a tone of the same frequency and the same amplitude as sound wave 1.
• sound wave 3 is made by a tone of higher frequency and the same amplitude as sound wave 1.

Explanation:

1. Frequency Analysis: Frequency is related to the number of cycles (waves) per unit time. Sound wave 1 has fewer cycles, while sound wave 3 has more cycles in the same time frame, indicating a higher frequency for sound wave 3.
2. Amplitude Analysis: Amplitude relates to the height (loudness) of the wave. The height of sound wave 3’s peaks (and troughs) appears similar to sound wave 1’s, suggesting the same amplitude.
3. Eliminating Other Options:

• Sound wave 2 has a larger amplitude (taller waves) than 1, so options about “four times amplitude” or “same amplitude as 2” are incorrect.
• Sound wave 3’s frequency is higher (more cycles) than 1, so “same frequency” options are incorrect.

(Note: The discipline here is Natural Science, subfield Physics, focusing on wave properties like frequency and amplitude.)

Answer:

Sound wave 3 is made by a tone of higher frequency and the same amplitude as sound wave 1.
