I Wonder Why – Why We Get Rainbows?

seven colors

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.
