1. A 473 Hz sound wave travels through a substance. The wavelength of the sound wave is measured to be 275 centimeters. What is the speed of sound in the substance in m/s?

2. Scientists in a laboratory produce a sound wave in a simulated environment (air) with a velocity of 419 m/s. What is the temperature (in Celsius) of the environment?

3. A test tone used on a radio has a frequency of 902 Hz. What is the wavelength of this sound in air at average room temperature (68 F). Record your answer to three decimal places.
