### Educational Content on Ultrasound and Echolocation**Question 9 of 22**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.**Problem 1:**What is the wavelength \( \lambda \) of this ultrasound, in meters?- \( \lambda = 0.01 \) m**Problem 2:**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?- *Distance from the bat: 5.25 m*---**Diagram Explanation:**There are no diagrams or graphs in this image.

we used the relation between frequency, wavelength and speed

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?
