Question

interpreting an oscilloscope graph
you can use an oscilloscope to learn the pitch (frequency) and loudness (amplitude) of a sound wave. the figures below show how to interpret the graph produced by an oscilloscope.
image a
the wave in the graph on the right has a larger amplitude than the one on the left. therefore, the sound represented by the right - hand graph is louder than the one represented by the left - hand graph.
image b
take a look

1. compare what is the amplitude of the graph on the right compared to the amplitude of the graph on the left? what is the wavelength of the graph on the right compared to the wavelength of the graph on the left?

Explanation:

Step1: Analyze Amplitude

Amplitude is the height of the wave from the midline to the peak. The right graph (in Image A) has a taller wave (greater vertical distance) than the left graph. So, the amplitude of the right graph is larger.

Step2: Analyze Wavelength

Wavelength is the distance between two consecutive peaks (or troughs). Both graphs in Image A have the same number of waves over the same horizontal grid length? Wait, no—wait, looking at Image A: both waves have two full cycles? Wait, no, the left wave: let's count the horizontal grid. Wait, actually, in Image A, both waves (left and right) have the same wavelength? Wait, no, wait the problem is about Image A (the top two graphs). Wait, no, the question is about the graph on the right (of the top two, Image A) vs left. Wait, no—wait, in Image A, the left wave and right wave: do they have the same number of cycles? Let's see: the left wave has two cycles? Wait, no, the left wave: from start to end, how many peaks? Let's count. The left wave: peak, trough, peak, trough? Wait, no, the left wave in Image A: let's see the grid. The right wave in Image A has a larger amplitude (taller), but the wavelength: the distance between peaks. Let's check the horizontal distance. Both waves (left and right in Image A) have the same wavelength? Wait, no, wait the problem is maybe about Image A? Wait, the question is: "What is the amplitude of the graph on the right compared to the amplitude of the graph on the left? What is the wavelength of the graph on the right compared to the wavelength of the graph on the left?"

Wait, for amplitude: the right graph (in Image A, top right) has a larger amplitude (taller wave) than the left (top left). For wavelength: the distance between two consecutive peaks. Let's see the horizontal grid. Both waves in Image A (top) have the same number of cycles over the same horizontal length? Wait, no, the left wave: how many cycles? Let's count the peaks. Left wave: peak, trough, peak, trough? Wait, no, the left wave in Image A (top left) has two peaks? Wait, no, looking at the graph: the left wave (top left) has two full cycles? Wait, no, the right wave (top right) also has two full cycles? Wait, so the wavelength (distance between peaks) is the same? Wait, no, maybe I'm wrong. Wait, the key is: amplitude is vertical height, wavelength is horizontal distance between peaks. So in Image A (top two graphs), the right graph has larger amplitude (taller), and same wavelength (since the distance between peaks is the same—both have two cycles over the same horizontal grid length). Wait, but maybe the question is about Image A. So:

Amplitude: The amplitude of the graph on the right is larger than the amplitude of the graph on the left (because the wave on the right is taller, reaching higher above and lower below the midline).

Wavelength: The wavelength of the graph on the right is the same as the wavelength of the graph on the left (because the distance between consecutive peaks (or troughs) is the same for both waves—they have the same number of cycles over the same horizontal span).

Answer:

Amplitude: The amplitude of the graph on the right is larger than that of the left.
Wavelength: The wavelength of the graph on the right is the same as that of the left.
