La luz: luz visible

The video tutorial explains the visible spectrum, which includes colors like red, orange, yellow, green, blue, indigo, and violet. It discusses how sunlight, or white light, contains all these colors and how they blend together. The formation of rainbows is explained as a result of white light being separated by raindrops or mist, demonstrating the concepts of refraction and reflection. The tutorial also introduces prisms and the process of dispersion, where different colors in white light are refracted by different amounts, leading to the separation of colors.

What is the visible spectrum?

• The spectrum of ultraviolet light

• The range of sound frequencies audible to humans

• The entire electromagnetic spectrum

• The range of light wavelengths that can be seen by the human eye

Which colors are part of the visible spectrum?

• Red, orange, yellow, green, blue, indigo, violet

• Red, green, blue, ultraviolet, infrared

• Yellow, cyan, magenta, black, white

• Orange, pink, brown, gray, black

How is a rainbow formed?

• By sunlight being absorbed by clouds

• By artificial lights in the sky

• By sunlight being refracted and reflected by water droplets

• By moonlight passing through a prism

What happens to light when it passes through a prism?

• It slows down and separates into different colors

• It disappears

• It speeds up and combines into a single color

• It remains unchanged

What is the process called when different colors in white light are separated?

• Diffusion

• Reflection

• Dispersion

• Absorption
