Question

explain the set up used by newton to obtain a spectrum.​

Answer 1

Explanation:

He used a very simple setup to obtain a light spectrum. He simply used a glass made prism and let the sunlight to be passed from that prism ,which created a simple light spectrum of seven colours (VIBGYOR).

Answer 2

The set-up used by Newton to obtain a spectrum is as follows -

• Newton took only a glass prism to obtain the spectrum.

• He used that glass prism in a bright morning when the sunlight was significantly available in the environment.

• He placed the glass prism in such a position,that the solar rays were able to pass through that glass prism.

• After passing through that glass prism the white solar rays were dissociated into seven colours of the spectrum in the VIBGYOR sequence.
