Rainbows

Front

What is a rainbow?

Back

A rainbow is a meteorological phenomenon that occurs when sunlight is refracted, reflected, and dispersed in water droplets, resulting in a spectrum of light appearing in the sky.

Front

What causes the colors in a rainbow?

Back

The colors in a rainbow are caused by the dispersion of sunlight into its component colors (red, orange, yellow, green, blue, indigo, violet) as it passes through raindrops.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, such as from air into water.

Front

What is dispersion?

Back

Dispersion is the process in which light is separated into its different colors when it passes through a medium, like a prism or raindrop.

Front

What role do raindrops play in forming a rainbow?

Back

Raindrops refract and reflect sunlight, which causes the light to spread out into a spectrum of colors, forming a rainbow.

Front

Which color of light has the longest wavelength?

Back

Red has the longest wavelength of visible light.

Front

Which color of light has the shortest wavelength?

Back

Violet has the shortest wavelength of visible light.

Front

What is reflection?

Back

Reflection is the bouncing back of light when it hits a surface, such as a mirror or water.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light, while refraction is the bending of light as it passes through different mediums.

Front

What is a prism?

Back

A prism is a transparent optical element that refracts light, typically made of glass or plastic, and can create a spectrum of colors.
