Color

In 1666, Isaac Newton's prism experiment revealed that white light is composed of various colors. Light behaves as a wave, reflecting or refracting when encountering new media. The degree of refraction depends on wavelength, with violet refracting the most and red the least. Colors are perceived by the brain as different wavelengths of visible light. Rainbows form when raindrops disperse light like a prism. Materials interact with light based on their properties, with black absorbing all wavelengths and white reflecting them. The color of objects is determined by the wavelengths they reflect, with red objects reflecting red wavelengths. The world appears colorful due to the brain's interpretation of light wavelengths.

What did Isaac Newton discover about white light using a prism?

• It cannot be split into different colors.

• It is composed of a single color.

• It is only composed of red and blue colors.

• It is made up of various visible colors.

Which color of light has the shortest wavelength and is most refracted?

• Red

• Green

• Blue

• Violet

How do raindrops create a rainbow?

• By reflecting light back

• By dispersing light like a prism

• By absorbing all light

• By changing the color of light

Why are solar panels typically dark in color?

• To reflect all light

• To emit light

• To refract light

• To absorb all wavelengths of light

Why are buildings in warm countries often painted white?

• To enhance color perception

• To increase light absorption

• To reflect sunlight and keep cool

• To absorb more heat
