1 A student carries out an experiment to investigate the relationship between the refractive

index, n and the reciprocal of sinus of refractive angle,r sin

1 of five mediums with different

density.

This experiment begin with put a perspex medium with refractive index of 1.49 on a sheet of white paper. The outline of the sides, ABCD are traced on the white paper as shown onDiagram 1.0. A ray of light from the ray box is directed along the 30 0 from normal line to thecentre of AB plane. The perspex slab is removed. The point of incident and the corresponding

point of emergence are joined as shown on Diagram 1.1. The respective angle, r is measuredwith a protractor.

Diagram 1.0 Rajah 1.0

The procedure is repeated with using different transparent medium as crown glass, flint glass,

rutile and gallium phosphate, where their refractive index are 1.52, 1.66, 2.40 and 2.91

Eksperimen ini dimulakan dengan meletakkan satu medium bongkah perspek yang mempunyai indeks biasan 1.49 di atas sehelai kertas putih. Sempadan ABCD bagi medium

perspeks tersebut dilukiskan seperti Rajah 1.0. Satu sinar cahaya dipancarkan 30 0 dari garisnormal tepat pada tengah-tengah satah AB. Kemudian bongkah perspek dialihkan . Titik-titik

yang telah ditandakan kemudian disambungkan dengan garis-garis lurus seperti yang ditunjukkan pada Rajah 1.1. Kemudian sudut biasan, r diukur menggunakan protraktor.

Kaedah eksperimen diulangi dengan menggunakan medium lutsinar seperti crown glass, flint glass, rutile dan gallium phosphate, di mana indeks niasan masing-masing ialah 1.52,1.66, 2.40 dan 2.90. Sudut tuju yang digunakan adalah sama. Sudut biasan bagi medium-medium tersebut ditunjukkan seperti pada Rajah 1.2, 1.3, 1.4 dan 1.5.
