The back of the book says that they are shorter then a single bond but longer then a double bond...... slightly confusing. Does it mean to say that they are larger then a single C-C bond but smaller then a C=C bond?<br /><br />Thank you!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7904228234595614222.post-30043193253173541842013-12-12T21:48:01.824-08:002013-12-12T21:48:01.824-08:00can you please give me an example?can you please give me an example?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7904228234595614222.post-9682735957638155452013-12-12T21:44:11.512-08:002013-12-12T21:44:11.512-08:00It will emit a photon of the same energy as the ba...It will emit a photon of the same energy as the band gap.Scott McIndoehttps://www.blogger.com/profile/00490846726020849904noreply@blogger.comtag:blogger.com,1999:blog-7904228234595614222.post-8966866531642089522013-12-12T21:41:24.355-08:002013-12-12T21:41:24.355-08:00How do you know what color a LED make produce?How do you know what color a LED make produce?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7904228234595614222.post-91839346062214618572013-12-12T21:39:07.689-08:002013-12-12T21:39:07.689-08:006565Scott McIndoehttps://www.blogger.com/profile/00490846726020849904noreply@blogger.comtag:blogger.com,1999:blog-7904228234595614222.post-85306837017285244022013-12-12T21:00:30.786-08:002013-12-12T21:00:30.786-08:00how many questions are on the final?how many questions are on the final?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7904228234595614222.post-52030741958503444232013-12-12T17:37:16.626-08:002013-12-12T17:37:16.626-08:00DDScott McIndoehttps://www.blogger.com/profile/00490846726020849904noreply@blogger.comtag:blogger.com,1999:blog-7904228234595614222.post-17559979361613146062013-12-12T17:32:34.996-08:002013-12-12T17:32:34.996-08:00I was just wondering what the answer to 65 on the ...I was just wondering what the answer to 65 on the 2012 december final was?
