The frequency of a sound is defined as the number of repetitions of its waveform per second, and is measured in hertz; frequency is inversely proportional to wavelength (in a medium of uniform propagation velocity, such as sound in air). The wavelength of a sound is the distance between any two consecutive matching points on the waveform.
The line — When your heart's on fire, smoke gets in your eyes — apparently comes from a Russian proverb. [ 3 ] By the time of Roberta in 1933, the tune had been composed for a tap dance in the 1927 musical Show Boat , but was not adopted; in 1932 it was retried as a march for a radio series theme tune.
It can also be used to trace the path of sound waves in a similar fashion to light waves, making it a viable option for more immersive sound design in video games by rendering realistic reverberation and echoes. [4] In fact, any physical wave or particle phenomenon with approximately linear motion can be simulated with ray tracing.
Acoustic microscopy is the technique of using sound waves to visualize structures too small to be resolved by the human eye. High and ultra high frequencies up to several gigahertz are used in acoustic microscopes. The reflection and diffraction of sound waves from microscopic structures can yield information not available with light.
A person from Cairo, reputed to possess the evil eye. [citation needed] The evil eye is a supernatural belief in a curse brought about by a malevolent glare, usually inspired by envy. [1] The belief in the evil eye among humans has existed for thousands of years, and amulets to protect against it have been found dating to around 5,000 years ago ...

The following is an abridged ...
The term echolocation was coined by 1944 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. [1] [2] As Griffin described in his book, [3] the 18th century Italian scientist Lazzaro Spallanzani had, by means of a series of elaborate experiments, concluded that when bats fly at night, they rely on some sense besides vision, but he did ...
