Wavelength Calculation | MCQs

Explanation

The wavelength of the audible frequency (20 Hz to 20 kHz) audible to the human ear is approximately 17 m to 17 mm.

Bats use slightly higher frequencies, so they can solve targets smaller than 17mm.

The wavelength of audible sound is much longer than the wavelength of visible light.

Explanation

Very high frequency is the ITU designation for the range of radio frequency electromagnetic waves from 30 to 300 megahertz,

with corresponding wavelengths of ten to one meter.
