Ultrasound frequencies range from 20 kHz (the upper range of hearing for a young adult human) through 150 kHz (audible to some bats and other creatures), right up to 10 MHz (used in some medical treatments and industrial cleaning applications). While these frequencies overlap with those of radio waves, they are different because sound and ultrasound are vibrations in the air, while radio waves are electromagnetic waves that can travel in a vacuum.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
