Question

the shortest wavelength emitted in air by a bat is about 0.33cm what is the highest frequency a bat can emit

Answer 1

λ = wavelength emitted by bat = 0.33 cm = 0.0033 m

v = speed of sound = 343 m/s

f = frequency emitted by bat = ?

frequency emitted by bat is given as

f = v/λ

f = 343/0.0033

f = 1.04 x 10⁵ Hz
