Newton argued that it was composed of particles, which he called corpuscles, while Huygens viewed it as a wave. The predominant viewpoint for a long time, probably because of the high esteem with which Newton was held in the scientific community, was his corpuscular theory: that light was composed of particles.<br /> <br /> However, that all changed with Thomas Young, an incredible English polymath, when he conducted what is now known as his Double Slit Experiment. This provided extremely compelling evidence that light is, indeed, a wave.<br /> <br /> <i>Please note, in order to understand why this result can only be explained by light being a wave, you should first understand <a href="http://www.phy.si/2012/02/constructive-and-destructive.html">constructive and destructive interference</a>.</i><br /> <br /> <iframe class="scribd_iframe_embed" data-aspect-ratio="1.41503267973856" data-auto-height="false" frameborder="0" height="400" id="doc_5283" scrolling="no" src="http://www.scribd.com/embeds/82608787/content?start_page=1&amp;view_mode=list&amp;access_key=key-1ywu1zlbzy2uhatt6ipt" width="100%"></iframe><br /> <div style="text-align: right;"> <a href="https://docs.google.com/open?id=0B1l6BiOa2lOmQzZDQ3I4RFpSbENHMmFReldlWVhUQQ">View in Google Docs</a>&nbsp;</div> <div style="text-align: right;"> <a href="https://docs.google.com/open?id=0B1l6BiOa2lOmTU5SX2NrcktSb21UN2hfU3B6MVBYdw">View as Handout</a></div> <div style="text-align: right;"> <br /></div> Try these questions:<br /> <br /> <iframe class="scribd_iframe_embed" data-aspect-ratio="0.706697459584296" data-auto-height="false" frameborder="0" height="400" id="doc_83532" scrolling="no" src="http://www.scribd.com/embeds/82609639/content?start_page=1&amp;view_mode=list&amp;access_key=key-1zuf6ke4tunob5pasn4g" width="100%"></iframe><br /> <div style="text-align: right;"> <a href="https://docs.google.com/open?id=0B1l6BiOa2lOmR25HNEhSSzZUQjJHYXZnbGlwRm1oUQ">View in Google Docs</a> </div> <br /> <br /><div class="blogger-post-footer"><script type="text/javascript"><!-- google_ad_client = "ca-pub-8370469387336722"; /* RSS feed for phy.si (blogspot) applets */ google_ad_slot = "4014057981"; google_ad_width = 468; google_ad_height = 60; //--> </script> <script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> </script><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4843069304381987103-3758758068111723792?l=www.phy.si' alt='' /></div><img src="http://feeds.feedburner.com/~r/physi/~4/_YqXPrt8_XA" height="1" width="1"/>http://feedproxy.google.com/~r/physi/~3/_YqXPrt8_XA/youngs-double-slit-experiment.htmlnoreply@blogger.com (Mr A)http://www.phy.si/2012/02/youngs-double-slit-experiment.htmltag:blogger.com,1999:blog-4843069304381987103.post-6795445817060977108Tue, 21 Feb 2012 20:35:00 +00002012-02-21T12:37:39.678-08:00AQA GCSE P1transversesoundlongitudinalAQA AS Unit 2earthquakeslightwaves<iframe class="scribd_iframe_embed" src="http://www.scribd.com/embeds/82327047/content?start_page=1&view_mode=list&access_key=key-2l1srzb93z9ijlo091c9" data-auto-height="true" data-aspect-ratio="0.707514450867052" scrolling="no" id="doc_42267" width="100%" height="400" frameborder="0"></iframe> <div style="text-align: right;"> <a href="https://docs.google.com/open?id=0B1l6BiOa2lOmM2NmMzlmMDAtNTE2ZS00MGI1LTk2YmYtMjcyYjIzYzRlMDBl">View in Google Docs</a></div> <div style="text-align: left;"> <br /> It is always useful, when talking about waves, to see these effects actually happening.

One is placed on a cork mat (an insulator) and one on a metal surface (conductor).

The ice cube on the metal has completely melted while the cork mat has hardly made a dent.&nbsp;</div> <div> <div> <br /></div> <div> This experiment also demonstrates that air (as with any gas) is a good insulator.
