KESUKARAN MENGAPLIKASIKAN HUKUM SNELL BAGI TAJUK PANTULAN & PEMBIASAN CAHAYA

Pembiasan Cahaya

Pantulan Cahaya

INDEKS BIAS

n = c/v

n = ialah indeks biasc = laju cahaya dalam vakum (3 x 10 )v = laju cahaya dalam bahan

8

Contoh soalan bagi indeks bias :

“Hukum Snell”

=

Sudut tuju

Sudut pantul / bias

= Indeks bias bahan pertama

= Indeks bias bahan kedua

Tutorials:

1. A beam of light is incident on a plane of mirror at an angle of 32°relatively to the normal. What is the angle between the reflected rays and the surface of the mirror?

A) Reflection

1. A beam of light enters water at an angle of 60° relative to the normal of the water surface. Find the angle of refraction ?

B) Refraction
