1. 1. A 600.0 Hz sound has a velocity of 1087.0 ft/s in the air and a velocity of 4920.0 ft/s in water. 
   1. a.what is the wavelength (in ft) of this sound in the air?
   2. b. what is the wavelength (in ft) of this sound in the water? 
   3. 2. How much time (in second) will elapse between seeing and hearing an event that happens 400.0 meters from you? (Note: assume the velocity of sound in dry air @ 20 C and use velocity = 343 m/s)
