I Wonder Why – Why We Get Rainbows? PR034 UNIV 17

Why do we get rainbows?

● Rainbows are spectacular rays of color. The sun makes rainbows when white

sunlight passes through raindrops. The raindrops act like tiny prisms.

● Three conditions must be met for you to see a rainbow. First, it must be

raining. Second, the sun must be shining. Third, the observer must be between

the sun and the rain. The lower the sun is in the sky, the higher the arc of the

rainbow will be.

● The night-time rainbow is very rare and occurs only when the moon is bright


enough and positioned properly to falling rain to produce the

beautiful effect.

● A double rainbow is a phenomenon in which, if the beam is reflected twice inside

of the water drop them it will cause a secondary rainbow to appear when the light

leaves the water drop. The colors of the secondary rainbow are reversed in

order with violet on the top and red at the bottom.
