How long does a rainbow in the sky live?

Answer 1

Rainbows are caused by sunlight glinting off tiny water particles in the sky, bouncing the light back towards the observer. In other words, any time you see a rainbow directly in front of you, the Sun is directly behind you, and your shadow points at the center of the circle the rainbow is describing.

This can last as long as the droplets and the Sun are in the right position, which makes it dependent on the weather, partly, and weather lasts as long as it feels like lasting!

for as long as the suns out or as long as the sun is shining on the water

Answer 2

A rainbow typically lasts for less than an hour, depending on various factors such as the angle of the sun, the presence of rain, and atmospheric conditions. Once the conditions that create a rainbow change, it will disappear.

Answer 3

it can last a couple min. or half an hour
