Question

A bat can hear frequencies upto 120 kHz considering the speed of sound to be 300 m/s.
a) Find the wavelength of the signal​

Answer 1

Answer:

2.5 mm

Explanation:

Wavelength = speed / frequency

= 300/120000 m

= 1/400 m

wavelength = 0.0025 m = 2.5 milimeter

Answer 2

Ans. 400 m

Explaination:

Frequency=120 khz or 120000 hz

Speed =300 m/s

S=wavelength × frequency

Wavelength=frequency / speed

=120000 / 300

Wavelength =400 m
