Room temperature is defined as 25°C. The speed of sound at room temperature is 346 m/s. An engineer is using a sound wave with a frequency of 1000 Hz to tune the sound level in a piece of equipment. i) Determine the wavelength and time for one oscillation in milliseconds. ii) Determine the new wavelength if the frequency is quadrupled.
