Light Dispersion and Color Theory

The video tutorial explains the concept of light dispersion, where white light splits into seven colors when passed through a prism. It discusses the formation of a spectrum, the deviation of colors, and the role of refraction. The tutorial also demonstrates Newton's disk experiment, showing how mixed colors appear white. Finally, it addresses questions about laser light and the nature of white light.

What is the process called when white light splits into seven colors?

• Dispersion

• Absorption

• Diffraction

• Reflection

Which optical instrument is used to demonstrate the dispersion of light?

• Telescope

• Prism

• Mirror

• Lens

In the spectrum formed by a prism, which color is least deviated?

• Blue

• Red

• Green

• Violet

What is the order of colors in the spectrum formed by dispersion?

• ROYGBIV

• VIBGYOR

• YORGBIV

• BIVGYOR

What happens when a Newton's disk is spun rapidly?

• It appears black

• It appears white

• It appears red

• It appears blue

What does the appearance of white on a spinning Newton's disk demonstrate?

• Colors are refracted

• Colors are mixed

• Colors are reflected

• Colors are absorbed

Which of the following is NOT considered a white light source?

• Sunlight

• Candlelight

• Laser light

• Tube light

Why does sunlight sometimes appear yellow?

• It contains only red and green light

• It is not actually white light

• Because it lacks blue light

• Due to atmospheric scattering

What is the scientific definition of white light?

• Light that is emitted by the sun

• Light that consists of all seven colors

• Light that is reflected by a mirror

• Light that appears white to the human eye

Why does laser light not undergo dispersion?

• It is too intense

• It is already split into colors

• It consists of only one color

• It is not affected by prisms
