5. Seven Colours of Sun Light
Seven colours mix together to become an intense glow of white rays of the Sun. Sir Isaac Newton; the renowned scientist of 16th century had been accredited with this Discovery.
Ages before Newton, the ancient Indian Vedic knowledge had revealed that the sunlight consists of seven colours.
Sun's seven coloured rays are making a day.
Does that mean sun has only seven rays? No, sun emits millions of rays. But each ray of light has seven colours embedded in it. The Vedic terminology often refers to word "saptha asva ruda". It actually actually means seven coloured white sunrays.
