Does Wavelength matter when it comes to the order of the colors in a rainbow? Why, or why not?

• Yes, because the shorter the wavelength, the further away it is from the sun.

• Yes, because the shorter the wavelength, the closer it is to the sun.

• No, because the shorter the wavelength, the further away it is from the sun.

• No, because the shorter the wavelength, the closer it is to the sun.

After rainfall, a rainbow forms, ALWAYS or SOMETIMES or NEVER, Why?

• Always, because the surface of the water droplet matters for the reflection, dispersion and refraction of the sun's white light.

• Sometimes, because the surface of the water droplet matters for the reflection, dispersion and refraction of the sun's white light.

• Never, because the surface of the water droplet matters for the reflection, dispersion and refraction of the sun's white light.
