a. The speed of the wave can be calculated using the formula:Speed = Distance / TimeGiven that the distance is 91.4 m and the time is 0.29 s, we can substitute these values into the formula:Speed = 91.4 m / 0.29 s = 316.55 m/sTherefore, the speed of the wave is 316.55 m/s.b. The wavelength of the wave can be calculated using the formula:Wavelength = Speed / FrequencyGiven that the speed is 316.55 m/s and the frequency is 192 Hz, we can substitute these values into the formula:Wavelength = 316.55 m/s / 192 Hz = 1.65 mTherefore, the wavelength of the wave is 1.65 m.c. The period of the wave can be calculated using the formula:Period = 1 / FrequencyGiven that the frequency is 192 Hz, we can substitute this value into the formula:Period = 1 / 192 Hz = 0.005208 sTherefore, the period of the wave is 0.005208 s.
