Quincke's tube

Dating

11 June 1929

It is a sound interferometer developed by the German physicist Georg Hermann Quincke (1834-1924) in the third quarter of the nineteenth century and then improved by Rudolf Koenig. With such an instrument is possible to study the interference of sound waves and get also a measure of the speed of sound when the vibration frequency of the sound source (usually a tuning fork on resonance box) is known.

The additional indications which integrate the items of the conservation's state have the following meaning: (?) = maybe complete; M = maintenance; P = partial; R = restored; D = used for teaching; NC = not checked; X = impossible to verify.

In order to avoid that instruments' cards without the english description text of the device be directly selected, I added a special filter with which only the complete cards are shown in the menu. Anyhow all the partial english instruments' cards (with instrument's dating, dimensions, state of conservation...) can always be seen even if they haven't the english description text. To read this uncomplete cards is sufficient to click, for example, on an instrument's picture or on the word "View" of the table column called "Card" every time they appear in the other pages of this database.
