If the source emits waves of an infinite number oflengths included between the red and the violet the infinite numberof partially overlapping images of the slit will form a continuous … Fig. 248. spectrum. If the slit is wide the different colors will greatly over-lap, and the spectrum is said to be impure. There is less over-lapping when the slit is narrowed; but, since no slit can be madeinfinitesimally narrow, it is manifestly impossible to obtain aperfectly pure spectrum. 437.…
