Explain the visible spectrum and the continuous spectrum.

(N/A) Visible Spectrum: White light contains waves of all wavelengths in the visible region. When a beam of white light is passed through a prism,it splits into a series of colored bands,which is called a 'spectrum'.
Continuous Spectrum: The visible spectrum ranges from violet $(7.50 \times 10^{14} \ Hz)$ to red $(4.00 \times 10^{14} \ Hz)$. This is a continuous spectrum. $A$ 'continuous spectrum' is one in which the adjacent colors (wavelengths) blend into each other without any gaps.
Example: In the visible spectrum,violet blends into blue,blue into green,and so on,with all colors merging into one another.
