What are UltraSonic Waves? Ultrasonic waves are sound waves with frequencies high about human hearing and short wave lengths. Sound waves have frequencies about 20‚000 to 100‚000. Also 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

Weird Animals Lesser water boatman ( Micronecta scholtzi): The loudest penis on Earth The lesser water boatman‚ just 2 millimetres long‚ is the loudest animal on Earth and more impressive fact is that he makes its noises using its penis instead of its mouth or legs or wings. James Windmill‚ engineering expert‚ in mid-2011 from the Centre for Ultrasonic Engineering at the University of Strathclyde (Scotland) reported in PLoS One that the lesser water boatman can produce sounds

1. How do you calibrate an Oscilloscope? In order to calibrate the Oscilloscope‚ we connected the BNC alligator into the channel we wanted to calibrate (Channel 1). We clipped the red probe to the calibration knob‚ and we saw a 2 volt VPP signal. The desired output from the oscilloscope was a 1000 Hz calibration frequency. The 1000 Hz frequency is the standard frequency for most of the oscilloscopes. After we clipped the red probe‚ we saw a square wave signal. The first thing we calibrated was the

This decision affects the bidding process in multiple ways. For one there is less time for the two bidding groups to come up with a price and resulting agreement. They are forced to act quickly and find
