O Attempt 4 Bats rely on sound localization to be able to fly during the night. On a cool 20°C summer night, a bat produces an ultrasonic sound with a frequency of 35 kHz. The speed of sound in air at 20°C is 340 m/s. What is the wavelength 1 of this ultrasound, in meters? %3D .01 m While remaining stationary, the bat emits a sound pulse and receives an echo after 0.150 s. How far away, in meters, is the reflecting object from the bat?
