This vibration microscope, which is in the form of an extremely large free standing cast iron tuning fork, has a round base decorated with acanthus leaves moulded in relief. The limbs are so long that a very low harmonic can be heard at the base of the limbs which is felt more than heard . This suggests the lower harmonic is around 10-30 cps. The instrument was used in Lord Kelvin's class demonstrations. | License: | http://www.hmag.gla.ac.uk/spirit/rights/ | Publisher: | Hunterian Museum and Art Gallery, University of Glasgow | Rights holder: | Hunterian Museum and Art Gallery, University of Glasgow | Subjects: | SCIENTIFIC COLLECTION : | Source: | Hunterian Museum | Creator: | Hunterian Museum and Art Gallery, University of Glasgow | Identifier: | http://www.huntsearch.gla.ac.uk/cgi-bin/... | Language: | en-GB | Go to resource |
