Where does the rainbow end? | Questions | Naked Scientists Because rainbows are made in the sky, they don't touch the ground So if you're on the ground, however far you walk, the end of the rainbow will always look as if it were on the edge of the horizon But what people don't realise is that rainbows are actually complete circles, and obviously a circle has no end
Why does the rainbow sometimes seem to end? | Science Questions I have been fortunate on a number of occasions to be fairly close to the end of a rainbow, 300 or 400 meters away, where you can see the actual end of the rainbow striking the ground If you look through it to see objects behind, you can see clearly that the coloured lines are on your side
Is it possible to reach the end of a rainbow? The thing about rainbows is that the shadow of your head is always in the direct center of them So no, you can never reach the end In a different sense, you are always at the end of the rainbow, you are at the pointed bit of the cone of the rainbow The person beside you has their own cone that they're at the end of too!
Have you ever experienced Driving through a rainbow. . . . ? You can see the end fine but you can't stand at the end- as the mad man says And be careful, studying a rainbow whilst you're driving - you may see stars too, if you drive off the road! Thank you you cleared up the first part makes better sense , but why could I see the different colored lights in the front of my car as I approached that point
Do rainbows follow the contours of the horizon? It's actually neither A rainbow is caused by sunlight hitting clouds or rain, and can usually only be seen if there is a background of dark clouds Sunbeams go into a raindrop, reflect off the back inside surface of the raindrop and come back out of the front
Can you make a huge prism, and disperse light in different colors? The CD peeling methods might be of interest to those, likeJMerrill, who wish to incorporate rainbows in artwork, and the equations shown might be of interest to those, like Colin2B, who wish to examine the mechanism of forming those rainbows--it turns out that one can even calculate the spacing of the ridges with some accuracy using a laser and
What makes petrol rainbows? | Naked Science Forum - The Naked Scientists Regular rainbows are formed by refraction ie splitting the spectrum, thin film rainbows occur by diffraction ie an interference pattern To follow up: "regular rainbows" are white light getting split into individual frequencies ("pure colors"), while "dead rainbows" are the whole spectrum minus some distinct wavelengths (depending on the
why do some things reflect? | Naked Science Forum - The Naked Scientists You end with total reflection of the incoming pulse, but with opposite phase If the string is able to flap free at one end, the string mass is effectively zero at this point, and the force on it will be zero Since energy is force times distance, no energy will propagate beyond the free-floating end
DIY Rainbow - how a rainbow forms | Experiments - The Naked Scientists Water refracts different colours different amounts so they end up leaving in different directions You can see this effect if you look at the reflection of a light in a glass, just before the reflection disappears it changes colour at an angle of about 40° to the incoming light
How does my brain store information? | Podcasts - The Naked Scientists Chris - Okay Hello Annie And just for those who are not necessarily in the know, the reason we get rainbows is because you end up with light entering raindrops So you need a rainy sky with a bright sun behind you to illuminate the rainy sky The rays of sunlight are coming in parallel and they're white
