Question:
The smallest insects that a bat can detect are approximately the size of one wavelength of the sound the bat makes (sonar). What is the minimum frequency of sound waves required for the bat to detect an insect that is 0.60 cm long? (Assume the speed of sound is 340 m/s.)

Explanation:

a. The formula that relates frequency and wavelength is

f

=

v

λ

where f is frequency, v is the velocity of propagation (velocity of sound in this case), and

λ

is the wavelength.

To detect this fly,

λ

needs to be

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
