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
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 The actual rainbow seems to be close to half a circle, but why does it appear to end there? Is it going
Do rainbows follow the contours of the horizon? Question Do rainbows follow the contours of the horizon, so the curvatire of the Earth gives the curve of a rainbow, or is it the sun? Can you also get a Moonbow?
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
Does latitude affect the frequency of double rainbows? A rainbow can only be seen when the sun is close to the horizon; the closer to the horizon the bigger the bow At higher latitudes the sun spends more time near the horizon, at a low enough angle for a rainbow to be seen So you are more likely to see rainbows at high latitudes than at the equator, (assuming weather is the same at both locations)
why do some things reflect? | Naked Science Forum 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
The MMR vaccine and vaccine hesitancy | Interviews The tables were turned very much against measles in the 1960s when the first mainstream vaccine was developed It was later rolled into a triple jab called MMR - which has been a cornerstone of public health, protecting us from measles, mumps, and rubella Its effectiveness hinges on very high levels of population uptake - in the region of 95% - which are needed to counter the exceptionally
How does my brain store information? | Podcasts - The Naked Scientists 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
Horizontal lightening | Naked Science Forum Then lightening darted from two clouds, under the arc of the rainbow, from one side to the other, it was really strange, it went from one cloud, horizontally through the rainbows arch, to another cloud Quite beautiful, or it would have been, but the meaning behind it just gave me the creeps instead
Seeing the stars with spectroscopy | Interviews It's connected to a long tube which has a thing in the end which I guess is the spectroscope So, if you point this at different things, will we see different kinds of rainbow on the screen?
