Lorentz(1853–1928)Hendrik Antoon Lorentz (1853–1928) adalah seorang fisikawanBelanda yang kali pertama me-ngemukakan tentang pemantulandan pembiasan cahaya, ditinjau dariteori bahwa cahaya termasukgelombang elektromagnetik. Teoriini dikembangkan oleh James ClerkMaxwell yang menyatakan bahwacahaya terdiri atas gelombang listrikdan gelombang magnetik dengansudut yang berbeda. Lorentz jugamemprediksi keberadaan elektron.Beliau menerima hadiah Nobeltahun 1902 dalam bidang fisika ataspenelitiannya mengenai medanmagnet. Dalam bab teori relativitas,Lorentz berjasa dalam teorinyamengenai "Transformasi Lorentz".Sumber: Science Encyclopedia, 1998Mudah dan Aktif Belajar Fisika untuk Kelas XII238B6@6 ++ + ++O + + +O @=>FCM6=6G>AHF6CG;DFB6G>'DF:CHN96E6H9>HIA>GG:76<6>7:F>@IH --O+) +-O+) -+)+..//O )+-)) ++-) +-)+O$/0 + ,7 9>@:BI@6@6CDA:=$,#/'),1--,-/$,16G:DF6C<;>G>@6K6C :A6C96E696 +:FG6B66CH:FG:7IH96E6H9>E6@6>ICHI@B:C<=>HIC<E6FH>@:A E6FH>@:AM6C<7:F<:F6@8:E6H /F6CG;DFB6G>'DF:CHN>C>6@6CH:F:9I@G>B:C?69>HF6CG;DFB6G>"6A>A:D6E67>A6@:A6?I6C+?6I=A:7>=@:8>A96F>@:A6?I6C86=6M6+ 2.Transformasi Kecepatan dari Lorentz+DGHIA6HF:A6H>J>H6G@=IGIGB:CM6H6@6C76=K6@:A6?I6C86=6M696A6BFI6C<=6BE6B:B>A>@>=6F<6M6C<G6B6ICHI@G:BI6E:C<6B6HH>96@7:F<6CHIC<E696<:F6@F:A6H>;CM6 .:7:F@6G86=6M6M6C<9>E6C86F@6C96A6B@:F6C<@668I6CE6966F6=<:F6@CM69:C<6C@:A6?I6C+F:A6H>;H:F=696E@:F6C<@66@6CB:B>A>@>@:A6?I6C+9>I@IF96F> .:@6F6C< C96H>C?6IG:GI6HIM6C<7:F<:F6@F:A6H>;H:F=696E@:9I6CM6M6>HI96C +:C<6B6H9>B:C<I@IF@:H><6@DBEDC:C@:8:E6H6C96A6BM6>HITantanganuntuk AndaDengan cara yang sama seperti padaPersamaan (9–21), turunkanpersamaan transformasi kecepatanrelativistik sehingga didapatkanhasil seperti Persamaan (9–22).Teori Relativitas Khusus239-././-++))) 96EICE:C<6B6H96A6BB:C96E6H-././-++))) :C<6CB:C9>;;:F:CG>6A@6C$/0 + ,7 9>E:FDA:= -+)-..//+ +)-)+G:=>C<<6 ---+)+-+--+))+)+++-)-)-)+ 6H6I ------++++++++++O :C<6C86F6M6C<G6B6 C96?I<66@6CB:C96E6H@6CHF6CG;DFB6G>@:8:E6H6CF:A6H>J>GH>@ICHI@GIB7I .96CGIB7I / +. .-+++++. .-++++O+/ /-+++++/ /-++++Tantanganuntuk AndaDengan menggunakan transformasiLorentz, buktikan bahwa kecepatancahaya untuk pengamat yang diamdan pengamat yang bergerakdengan kecepatan v adalah sama.Mudah dan Aktif Belajar Fisika untuk Kelas XII240Gambar 9.8Sebuah meteran yang bergeraksebesar 87% dari kecepatancahaya, panjangnya hanya terlihatsetengahnya oleh pengamat yangdiam.3.Akibat Prinsip Relativitas Khususa.Kontraksi Lorentz/:DF>F:A6H>J>H6GB:B76K6E:C<6FI=H:F=696EE:C<I@IF6CE6C?6C<GI6HI7:C96M6C<7:F<:F6@H:F=696EG:DF6C<E:C<6B6H +:FI76=6CE6C?6C<GI6HI7:C966@>76H<:F6@6CF:A6H>;E:C<6B6H6H6I7:C969>G:7IH $#)' ( $'#)/6H6I%#.*(*)#%# # !# ) $#)') $# +6C?6C<6H6I?6F6@7I@6CA6=G:GI6HIM6C<BIHA6@H:H6E>G:GI6HIM6C<F:A6H>; +69696G6FCM6ICHI@B:C<I@IF?6F6@ C96=6FIGB:A>=6H@:9I9I@6C9I6H>H>@G:86F6G:F:CH6@ #I7IC<6C?6F6@6CH6F69I6@:F6C<@668I6C96E6H9><6B76F@6C9:C<6C86F6G:9:F=6C6G:E:FH>7:F>@IH>C> .:7I6=GIB7:F86=6M6 E696@:F6C<@668I6C7:F<:F6@9:C<6C@:8:E6H6C+H:F=696E@:F6C<@668I6C .I6HI@:A>E86=6M69>E6C86F@6C96F>GIB7:FH:FG:7IH96C9>E6CHIA@6CDA:=G:7I6=8:FB>C M6C<7:F?6F6@ 96F>GIB7:F .:76<6>68I6C9>H:BE6H@6CG:7I6=B>GH6F9>6BM6C<9><IC6@6CICHI@B:C6C96>?6F6@M6C<9>H:BEI=DA:=86=6M6EIA6C<76A>@96F>GIB7:F@:8:FB>C96C@:B76A>@:GIB7:F 26@HI)M6C<9>E:FAI@6CICHI@EIA6C<E:F<>86=6M6H:FG:7IH696A6=G:76<6>7:F>@IH )O C96>@6CE6C?6C<B>GH6FM6C<9>6B6H>96F>@:F6C<@6696A6=96CK6@HIM6C<9>E:FAI@6CDA:=@:A>E86=6M67:F<:F6@96F>GIB7:F@:8:FB>C696A6=)B6@6E6C?6C<A>CH6G6CHDH6A96F>GIB7:F@:8:FB>C7I@6CB:A6>C@6C696A6=+) O*A:=@6F:C6@:A>E86=6M67:F<:F6@9:C<6C@:8:E6H6CB6@6) O.:7I6=E:G6K6H6C<@6G6 7:F@:A6?I6C H:F=696E IB> %>@6E:G6K6H6C<@6G6 B:A:K6H> 9:C<6C@:A6?I6CF:A6H>; H:F=696EE:G6K6H 7:F6E6@6=@:A6?I6CE:G6K6H H:F=696E IB> 4 ! :C<6CB:C<<IC6@6C$/0 + ,7 9>E:FDA:= ---+++++ -+%69>@:A6?I6CE:G6K6H F:A6H>;H:F=696E IB> A:7>=@:8>A96F>@:8:E6H6C86=6M6 (:CIFIHB:@6C>@6@:8:E6H6CE:G6K6H H:F=696E IB> >C>H>96@BIC<@>CContoh 9.2Next >
