In the realm of waves, such as light or sound, the relationship between wavelength, frequency, and

Question

amplitude plays a crucial role in understanding their characteristics. Wavelength refers to the
distance between two consecutive points in a wave that are in phase, meaning they have the same
position in their respective cycles. Frequency, on the other hand, represents the number of complete
cycles or oscillations that a wave completes in a given time interval, typically measured in hertz (Hz).
The higher the frequency, the shorter the wavelength, and vice versa. Amplitude, on the other hand,
describes the maximum displacement of a wave from its equilibrium position. It determines the
intensity or strength of the wave, with greater amplitudes conveying more energy. Consequently,
these three properties are interconnected; a higher frequency wave will have a shorter wavelength
and can carry more energy, resulting in a larger amplitude. Understanding the relationship between
wavelength, frequency, and amplitude allows us to comprehend the behavior and characteristics of
various waves in different contexts.

4. Look at the following two sound waves. How would you describe their frequency and amplitude
in comparison to one another? Make sure to explain both of the sound waves

Answer 1

Regarding the two sound waves, their frequency and amplitude can be described in comparison to each other.

Frequency refers to the number of complete cycles or oscillations that a wave completes in a given time interval. Looking at the two sound waves, if one wave has a higher frequency than the other, it means that it completes more cycles in the same time interval. On the other hand, if one wave has a lower frequency, it completes fewer cycles in the same time interval.

Amplitude, on the other hand, describes the maximum displacement of a wave from its equilibrium position. It represents the intensity or strength of the wave. In the context of sound waves, amplitude determines the loudness of the sound. A larger amplitude corresponds to a louder sound, while a smaller amplitude corresponds to a softer sound.

Based on these explanations, we can compare the frequency and amplitude of the two sound waves:

Frequency:
If one sound wave has a higher frequency than the other, it means that it completes more cycles in the same time interval. In this case, we can say that the wave with a higher frequency has a higher pitch. In contrast, if one sound wave has a lower frequency, it completes fewer cycles in the same time interval, resulting in a lower pitch.

Amplitude:
Comparing the amplitudes of the two sound waves allows us to determine their relative loudness. If one sound wave has a larger amplitude than the other, it means that it has a greater maximum displacement from its equilibrium position. Consequently, it will be louder. Conversely, if one sound wave has a smaller amplitude, it means that it has a smaller maximum displacement and will be softer.
