why rainbow is curved shaped

Answer 1

Hey Mate,

Here Is Your Answer


____________________________

When making a rainbow, sunlight shining into each individual raindrop is refracted, or split into its component colors. And the light is also reflected, so that those various colors come bouncing back. One key to rainbows is that the light leaves the collection of raindrops in front of you at an angle.
