What does the Latin scientific phrase 'experimentum crucis,' used by Newton, translate to in English?
What happened when Isaac Newton isolated a single red ray of light and passed it through a second glass prism?
diego An inverted second prism reverses the initial split to recreate the original beam.
What other optical tool besides an inverted prism did Newton use to focus the split colors back into white light?
How did Isaac Newton physically prove that white light is made of all the colors of the rainbow combined?
Rainbow order: Newton's famous acronym ROYGBIV (Red, Orange, Yellow, Green, Blue, Indigo, Violet) is still taught to school children worldwide to remember the order of colors.
diego Spin the singing color wheel to discover how Newton connected light to musical notes.
Which two colors did Newton introduce to the spectrum specifically to represent the half-steps in his musical scale analogy?
Why did Isaac Newton decide to classify the rainbow into exactly seven distinct colors?
A transparent optical element with flat, polished surfaces that refracts and disperses light. Isaac Newton used a second inverted glass prism to recombine the colored spectrum back into white light.
