Perkembangan Radiasi Benda Hitam dan Kecocokan Teori Rayleigh - Jeans

Abstract

Ilmu Fisika mengalami perombakan pada abad 19, terutama pada tenaga radiasi. Keyakinan lama bahwa tenaga yang bernilai kontinu, ternyata adalah bernilai diskret. Hal ini juga menjadi tonggak awal Fisika Modern sebagai lahan ilmu fisika kuantum. Pemicu pemikirian mendasar ini adalah ditemukannya fenomena Radiasi Benda Hitam (Black Body) yang tidak bisa dijelaskan oleh Fisika klasik. Benda hitam itu sendiri adalah suatu benda yang dapat menyerap semua radiasi yang datang kepadanya. Kemudian radiasi yang dipancarkan oleh benda hitam itu sendiri dinamakan Radiasi Benda Hitam. Rayleigh-Jeans mencoba memecahkan fenomena radiasi benda hitam dengan mengajukan teori berdasarkan fisika klasik yang memiliki kesimpulan bahwa tenaga rata rata hanya bergantung pada temperatur. Namun, teori Rayleigh-Jeans hanya cocok untuk nilai frekuensi endah dan tidak cocok untuk frekuensi besar khususnya daerah ultraviolet pada data eksperimen radiasi benda hitam yang tingkat energinya berangsur angsur naik sampai batas tertentu, kemudian turun lagi. Nilai frekuensi rendah yang membuat teori Rayleigh-Jeans cocok adalah bahasan utama makalah ini.
