No it's fog. The effect has even a special name and Wikipedia entry here.Andy SV said:
Rainbows appear curved because they are formed by the refraction and reflection of light through water droplets in the atmosphere. The light is bent as it enters and leaves the water droplets, creating a curved shape.
No, the curvature of a rainbow can vary depending on the size and shape of the water droplets in the air. It can also be affected by the angle at which the sunlight enters the droplets.
No, a full rainbow is actually a complete circle, but since the ground usually obstructs the bottom half, we only see a semi-circle. However, if you are high enough, like on a mountain or in an airplane, you may be able to see a full rainbow.
Rainbows have different colors because white light from the sun is made up of all the colors of the visible spectrum. When the light is refracted and reflected through the water droplets, it separates into its component colors, creating the rainbow.
No, a rainbow can only appear in a curved shape because the light is always refracted and reflected at a specific angle. This angle determines the curvature of the rainbow, and it cannot form in any other shape.
