Ia belajar di Munich danBerlin. Seperti banyak ahli fisikalainnya, ia seorang pemain musikyang pandai. Pada tahun 1900 M,setelah 6 tahun belajar di UniversitasBerlin, ia menyatakan bahwa kuncipemahaman radiasi benda hitamadalah anggapan bahwa pemancarandan penyerapan radiasi terjadi dalamkuantum energi hf. Penemuan yangmenghasilkan hadiah Nobel 1918 inisekarang dianggap sebagai tonggakdari fisika modern. Walaupun selamaHitler berkuasa, ia tetap tinggal diJerman. Ia memprotes perlakuanNazi kepada ilmuwan Yahudi dansebagai akibatnya ia harusmelepaskan kedudukannya sebagaipresiden Institut Kaiser Wilhelm.Setelah perang dunia kedua, instituttersebut diberi nama Institut Planckdan ia kembali menjabat sebagaipresiden sampai akhir hayatnya.Sumber: Fundamental Of Physics, 20011m2m3mMudah dan Aktif Belajar Fisika untuk Kelas XII18036?529:D2>5:D6B2?8<2?@=69 46) &=1*.,- M 52?!.6&2*745;&6)*&37 M *6BE>EC2?>6B6<2>6?88E?2<2?D6@B:7:C:<2<=2C:<C6A6BD:D6@B:<:?6D:<82C :%6=2C1#?52D6=29>6>A6=2;2B:>2D6B:A2?2C36?5236B9E3E?82?56?82?6?6B8:<:?6D:<>@=6<E=82C -6@B:6<:A2BD:C:>6?I2D2<2?329G26?6B8:D@D2=82C52=2>CE2DEBE2?82?D6BDEDEA5:328:C642B2>6B2D2<6C6D:2A>@=6<E=I2?8D6B52A2D5:52=2>BE2?82? $:<26?6B8:D@D2=C:CD6>252=2952?32?I2<?I2>@=6<E=I2?836B25252=2>BE2?82?252=296?6B8:B2D2B2D2I2?85:>:=:<:@=69C6D:2A>@=6<E=252=29 ?6B8::?:D6B<2?5E?852=2>36?DE<6?6B8:<:?6D:<C6D:2A>@=6<E= <2?D6D2A:D:52<36B2BD:C6>E2>@=6<E=>6>:=:<:6?6B8:I2?8C2>2I2:DE (:=2:D6BC63ED92?I2=29>6BEA2<2??:=2:B2D2B2D2 &2'&6 >6>A6B=:92D<2?C632B2?<646A2D2?I2?85:>:=:<:>@=6<E=82C ,632B2?6?6B8:<646A2D2?<2B6?26?6B8:<:?6D:<C6=2=E36B9E3E?82?56?82?<646A2D2? &=1*.,-*&37>6=:92D329G2<EBF2C632B2?:DEC6BEA256?82?92C:=I2?85:A6B@=69A252:?D6?C:D2CCA6<DBE>B25:2C:D6B>2= '6B6<236B2?882A2?252<6>:B:A2?2?D2B2C:72DA2?2C36?5252?B25:2C:D6B>2= 6?82?A6?56<2D2?I2?8>6B6<2=2<E<2? &=1*.,-*&37>6>A6B@=69A6BE>EC2?329G2:?D6?C:D2CB25:2C:36B32?5:?8D6B32=:<56?82?A2?8<2D6>A2DA2?;2?886=@>32?8 .?DE<I2?836C2B:?D6?C:D2C2<2?C6>2<:?<64:= A23:=2>6?56<2D:D2<9:?882:?D6?C:D2C2<2?>6?56<2D:?@= "2=:?:C6CE2:56?82?92C:=6>A:B:C <2?D6D2A:2A23:=2>6?56<2D:?@=92=:?:C2?82D>6?I:>A2?852B:92C:=6>A:B:CI2?8>6?E?;E<<2?329G2:?D6?C:D2C>6?56<2D:?@=<6D:<2C6>2<:?>6?864:= *6?I:>A2?82?A6BC2>22?+2I=6:89$62?CI2?8C2?82D;2E9:?:5:?2>2<2?N 6?42?2.=DB2/:@=6DO<2B6?2I2?8<64:=36B25252=2>G:=2I2986=@>32?8E=DB2F:@=6D &2'&6 >6?E?;E<<2?9E3E?82?:?D6?C:D2C52?A2?;2?886=@>32?82?D2B2<EBF2+2I=6:89$62?C52?<EBF20:6? -6@B:%.*352A2D>6?6B2?8<2?CA6<DBE>A252A2?;2?886=@>32?8I2?8A6?56<D6D2A:>6?I:>A2?8<6D:<2>6?6B2?8<2?A2?;2?886=@>32?8I2?8A2?;2?8 ,632=:<?I2D6@B: &=1*.,-*&3752A2D>6?6B2?8<2?CA6<DBE>A252A2?;2?886=@>32?8I2?8A2?;2?8D6D2A:>6?I:>A2?8<6D:<2>6?6B2?8<2?A2?;2?886=@>32?8I2?8A6?56< 4.Teori Planck-6@B:<=2C:<D6?D2?84292I2C63282:86=@>32?86=6<DB@>28?6D:<52A2D>6?;6=2C<2?52B:>2?22C2=B25:2C:<2=@BD6D2A:D:52<3:C256?82?D6A2D>6>AB65:<C:<2?CA6<DBE>4292I2I2?85:A2?42B<2?C63282:>2?2I2?8D6B2>2D:@=69%.*3 -6@B:%.*3>2>AE>6?;6=2C<2?B25:2C:36?529:D2>E?DE<A2?;2?886=@>32?8I2?8A6?56<D6D2A:8282=E?DE<A2?;2?886=@>32?8I2?8A2?;2?8 ,632=:<?I2D6@B: &=1*.,-*&3736B92C:=>6?;6=2C<2?B25:2C:36?529:D2>E?DE<A2?;2?886=@>32?8I2?8A2?;2?8D6D2A:8282=E?DE<A2?;2?886=@>32?8I2?8A6?56< <9:B?I2A6?;6=2C2?I2?8>6>E2C<2?=29:B52B:C6@B2?87:C:<2G2?$6B>2? &< 1&3(0 M #2>6?4@32>6=2<E<2?A6?56<2D2?=2:?56?82?>6?82;E<2?CE2DEBE>EC6>A:B:C52?D6B?I2D2C2?82D4@4@<56?82?92C:=A6?82>2D2??I2 vn (v)Gambar 7.5Sebaran jumlah partikel yangmemiliki kecepatan (v).Teori Rayleigh - JeansTeori WienIntensitasPanjang gelombangTeori PlanckGambar 7.6Perbandingan teori Wien, danteori Rayleigh-Jeans denganteori Planck yang memenuhidata percobaan.Tugas Anda 7.1Carilah dari buku-buku tentangformula yang digunakan Rayleigh-Jeans untuk menjelaskan intensitasradiasi benda hitam.Next >
