What is Color? Flame Challenge Winner 2014

The video explores the concept of color, starting with the idea that color is a wavelength of light. It explains how different wavelengths correspond to different colors, with white light being a combination of all colors. The video then discusses how objects reflect and absorb colors, using a red car as an example. It further delves into how the eye perceives color through photoreceptor cells, specifically rods and cones, and how the brain processes these signals to perceive color. The video concludes by highlighting the mysterious nature of color as a wavelength, reflection, signal, and perception.

What is the relationship between color and wavelength?

• Colors are determined by the speed of light.

• Colors are determined by the wavelength of light.

• Colors are determined by the direction of light.

• Colors are determined by the intensity of light.

What happens to the colors that are not reflected by an object?

• They disappear completely.

• They are absorbed by the object.

• They change into other colors.

• They are reflected back as white light.

Which cells in the eye are responsible for perceiving color?

• Rods

• Cones

• Photoreceptors

• Neurons

How do cones in the eye respond to red light?

• Blue cones respond the most, red cones less, and green cones the least.

• Red cones respond the most, green cones less, and blue cones the least.

• Green cones respond the most, blue cones less, and red cones the least.

• All cones respond equally.

What is one cause of colorblindness?

• One or more types of cones are not working properly.

• The rods in the eye are overactive.

• All cones in the eye are functioning properly.

• The brain cannot process any color signals.
