Diffraction refers to specific kind of interference of light waves. It has nothing to do with true rainbows, but some rainbow-like effects (glories) are caused by diffraction. Reflection and Transmission refer to what happens when light traveling in one medium encounters a boundary with another.

Is a rainbow refraction or diffraction?

The spreading of white light into its full spectrum of wavelengths is called dispersion. Rainbows are produced by a combination of refraction and reflection and involve the dispersion of sunlight into a continuous distribution of colors.

What causes rainbow formation?

The common rainbow is caused by sunlight internally reflected by the backs of falling raindrops, while also being refracted at the air/water boundary. The sunlight in this picture is coming from behind the observer, and the rainbows are in the rainstorm. The brightest rainbow is the primary rainbow.

Is rainbow caused by scattering?

Over most of the disc, scattered light at all wavelengths overlaps, resulting in white light which brightens the sky. At the edge, the wavelength dependence of the scattering gives rise to the rainbow.
