Question
When a compact disc is illuminated by a source of white light, coloured lines are observed. This is due to :
Options
A.dispersion
B.diffraction
C.interfrace
D.reference
Solution
A compact disc contains many fine circular lines on it acts different grating. When white light falls upon it it is diffrection as a result of which different colours bare different colours when we look at it through different angles.
