Newton's Disc Experiment Concepts

The video tutorial by Ken on Kids Fun Science demonstrates an experiment called Newton's Reverse Rainbow. It requires materials like sharpies, a CD, and string. The process involves marking, cutting, and assembling a disc to observe how spinning it blends colors into white light, illustrating Newton's theory that white light is a combination of all rainbow colors. The video explains the science behind this phenomenon, known as persistence of vision, and concludes with additional content.

What is the main focus of the experiment introduced in the video?

• Creating a rainbow with water

• Demonstrating Newton's disc and reverse rainbow

• Building a model of the solar system

• Exploring the phases of the moon

Which of the following is NOT a material needed for the experiment?

• Water

• Sharpies

• CD

• Glue stick

What is the purpose of marking the CD on a piece of paper?

• To test the sharpness of the pen

• To measure the CD's diameter

• To find the center point for sectioning

• To create a decorative pattern

What is used to poke holes in the cardboard disc?

• A screwdriver

• A needle

• A skewer or toothpick

• A pen

How long should the string be for the experiment?

• 36 inches

• 24 inches

• 12 inches

• 48 inches

What happens to the colors on the disc when it spins fast?

• They disappear completely

• They blend into white

• They fade to black

• They become more vibrant

What is the phenomenon called that explains the blending of colors into white?

• Color saturation

• Persistence of vision

• Optical illusion

• Color inversion

Who invented the Newton disc experiment?

• Nikola Tesla

• Albert Einstein

• Isaac Newton

• Galileo Galilei

What does the experiment prove about white light?

• It is only composed of red, green, and blue

• It cannot be broken down into other colors

• It is colorless

• It is made up of all colors in the visible spectrum

What is the result when using only red, green, and blue on the disc?

• The disc yields the same white light result

• The disc turns black

• The disc becomes transparent

• The disc remains colorful
