Rainbows do not 'produce' light. Classic rainbows appear whenever the sun is visible and there are small raindrops in the sky in the direction opposite the sun.
Imagine a ray from the sun hitting a drop that is directly above the spot that is opposite the sun. The sun's ray will enter the drop and, if the angle is right, bounce off the back of the drop and come out deflected by a characteristic angle, the "rainbow angle". If the drop is the right number of degrees above the antisolar point, the ray will will bounce off the back of drop and travel to your eye. You will thus see reflected sunlight that appears to be coming from a point that is above the the antisolar point by an angle equal to the rainbow angle.

Rays leaving raindrops after three reflections produce a tertiary rainbow. Unlike the primary and secondary bows which are opposite the sun and centered on the antisolar point, the tertiary appears sunwards and centered on the sun.

A rainbow is a circular arc of light that forms when sunlight interacts with raindrops in the atmosphere. The size of a rainbow can vary, but they are typically seen as a semicircle with a diameter of around 42 degrees centered on the antisolar point.

Yes, a rainbow would appear as a full circle when observed from space because it forms a complete circle around the antisolar point, which is directly opposite the sun. This phenomenon is called a "full-circle rainbow" or a "360-degree rainbow."

A rainbow forms a circular arc in the sky, with its center located at the antisolar point, which is the point directly opposite to the sun. However, when viewed from the ground, only a portion of the arc is usually visible to the observer due to the horizon.

A rainbow is produced by the refraction and reflection of sunlight through water droplets in the air. Sunlight is bent, or refracted, as it enters the water droplet and then reflects off the inside surface before exiting and dispersing into its various colors due to their different wavelengths.

An inflection point is not a saddle point, but a saddle point is an inflection point.
To be precise, a saddle point is both a stationary point and an inflection point. An inflection point is a point at which the curvature changes sign, so it is not necessary to be a stationary point.
