COVID Update
Good evening everyone,
it’s great news that things are starting to stabilize in Jersey and I really hope that things get better for all of us, we are now have 4 hours and to do the things we want to do which for me is photography so that’s fantastic I’m looking forward to sharing some of my future images with you…
I thought I’d chat around rainbows this evening there’s been a fair few around lately including this which was around a little while ago.I think quite lucky to be in the right place at the right time with rainbows in Jersey but other times I’ve been driving didn’t have my camera with me and there have been the most beautiful sites
Here’s a bit on how they are created by nature
A rainbow is formed when light (generally sunlight) passes through water droplets hanging in the atmosphere. … When light reflects off a water droplet, it simply bounces back in the opposite direction from where it originated. When light refracts, it takes a different direction.
Most raindrops are spherical rather than the often depicted ‘teardrop’ shape and it is this spherical shape that provides the conditions for a rainbow to be seen.
The position of the sun and the raindrops in relation to the observer need to be just right for a rainbow to form:
- The sun needs to be behind the viewer
- The sun needs to be low in the sky, at an angle of less than 42° above the horizon. The lower the sun in the sky the more of an arc of a rainbow the viewer will see
- Rain, fog or some other source of water droplets must be in front of the viewer
The size of the raindrops does not directly affect the geometry of a rainbow, but mist or fog tends to disperse the effect more (see fogbows).
Rainbows only appear semi-circular over level ground at sunrise or sunset, when the sun is exactly on the horizon, the majority of the time a smaller segment of an arc is seen. The bible also mentions rainbows in that God would never flood the earth again after the great flood of Noah’s day.
