Each wavelength of light is refracted to a different degree by the water, so each droplet acts as a tiny prism breaking the sun-light into its component wave-lengths. The rainbow is the result of effectively a huge mass of extremely small, natural prisms.

Incidentally, I have see one rainbow that was almost entirely yellow light only - a strange event and I feel privileged to see it, but I can't explain it, only suggest that the other colours were scattered or absorbed by thin, intervening mist.
To get refraction, all you need is light passing from one medium into another one
where its speed is different.
The speed of light is different in air and water.

Yes, it does refract light.
No, opaque substances can NOT refract light. It is impossible to refract light if it is blocking it's path.

a prism can be used to refract wight light
light travels in straight path and when speed of medium in which light travels change then it refract due to change in speed light rays bend and refract
Rain droplets can refract light. Different colours refract in different amounts so a spectrum is produced.

White light is really all the colors of light, red to indigo, combined together. Running the light through a prism (including raindrops) splits those colors out separately because each light bends a little more or less than its neighboring colors when going through the prism (or raindrops).

A prism refracts light, and a mirror reflects light.
a lens will refract light. a mirror will reflect the light.
Refract light. They only reflect when you see a glare or ghost image
A prism is a triangular shape used to refract light into its component colors.
