A wave is a phenomenon that carries energy without carrying matter. They can be classified in various ways, including the direction of particle vibration in relation to the wave propagation direction. Considering a sound wave propagating in the air, where the speed of sound is approximately 340 m/s, a student observes that between two consecutive peaks of air compression, there is a distance of 1.7 m. Considering the definition of wavelength (λ) as the distance between two identical points in a wave, and the frequency (f) of the sound wave, which is the number of cycles that repeat in one second, perform the following calculations: 1. Determine the frequency of the sound wave observed by the student. 2. If the sound source is altered in such a way that the distance between two consecutive peaks of air compression becomes 0.85 m, what will be the new frequency of the sound wave emitted by the source? Consider that the speed of sound in the air remains constant and that the sound source emits a continuous and uniform sound.
