Final answer:
A 2-kHz sound wave is a type of mechanical longitudinal wave that travels in the x-direction. Its behavior is determined by its characteristics like wavelength, amplitude, and speed. Higher frequencies correspond to shorter wavelengths, impacting the wave's interaction with its surroundings and how it is perceived by the listener.
Step-by-step explanation:
A 2-kHz sound wave is a type of mechanical longitudinal wave that travels in the x-direction. It has a frequency of 2,000 hertz, which means that 2,000 wave crests pass a point per second. The behavior of the sound wave is determined by its characteristics, such as wavelength, amplitude, and speed.
Wavelength is the distance between two wave crests or troughs. In the case of the 2-kHz sound wave, the wavelength can be determined using the formula:
Wavelength = Speed / Frequency
Amplitude refers to the height of the sound wave's crests above the null point. The amplitude of the wave determines its volume or intensity. The speed of sound in air is approximately 343 meters per second, so the wavelength of the 2-kHz sound wave would be:
Wavelength = 343 / 2000 = 0.1715 meters
The direction of the wave propagation is in the x-direction, which means the wave travels horizontally.
The factors such as frequency and direction impact the wave's behavior. Higher frequencies correspond to shorter wavelengths, which means the wave will have more wave crests per unit distance. This affects how the wave interacts with its surroundings and how it is perceived by the listener. Additionally, the direction of the wave determines the path it takes and how it interacts with obstacles or boundaries.
