A bat flying in complete darkness emits high frequency sound of 100 kHz to locate objects.The sound travels with a speed of 340 m/s in air.The wavelength of the sound produced by the bat is
A)3.4 m.
B)20.5 cm.
C)10.2 mm.
D)3.4 mm.
E)1.8 mm.

Question

Quizplus · Accepted Answer

The formula for wavelength is given as:

wavelength = speed of sound / frequency

Substituting the given values, we get:

wavelength = 340 m/s / (100,000 Hz)

wavelength = 0.0034 m = 3.4 mm (since 1 m = 1000 mm)

Therefore, the wavelength of the sound produced by the bat is 3.4 mm, which is option D.
