- A bat can detect small objects, such as an insect, whose size is approximately equal to one wavelength of the sound the bat makes. If bats emit a chirp at a frequency of 5.89 104 Hz, and if the speed of sound in air is 343 m/s, what is the smallest insect a bat can detect?mmOcean waves with a wavelength of 40.0 m travel at 5.00 m/s towards a boat at sea. Determine the number of times the boat bobs up and down per minute as a result of encountering the waves.During a thunderstorm, 3.0 s elapses between observing a lightning flash and hearing the resulting thunder. Approximately how far away in kilometers and miles was the lightning flash? (Assume the speed of sound is 344 m/s.) km mi
