The physics of a rainbow

Last week I had the urge to paint a rainbow. A few rainbows in fact, while experimenting with new watercolour brushes.

Rainbows just feel so happy and inspiring; I think most people enjoy the fleeting appearance of one in the sky. It feels magical and special.

Whenever I see one I feel the need to stare it down until it flits away; not let it get away too fast but then of course those bright arcs of colour dissolve right before my eyes.

The physics of a rainbow

I read an article about the physics of a rainbow, and rearranged the words and sentences to make my own ‘rainbow-logic’. It reads something like this:

The image hovering between the clouds was formed by streaming sunlight. Sunlight reflected back towards us suspended in myriad tiny raindrops. Two refractions conspire to concentrate each wavelength of light. Parallel rays entering a spherical raindrop, bounce inside, and the angle of refraction depends on the light; it’s wavelength as it hits the surface. Wavelength corresponds to familiar bands of colour…

Meanwhile, selfishly I’ve been keeping my inspirations to myself since embracing 2017, and haven’t sent out my regular monthly inspiration-mail while I consider what I want to do, where I want to be and what it will take to get me there. I’m taking my time to bloom into the year.

I hope you enjoy these rainbows in the meantime – see you on the other side.

    I’m very glad to hear you’ve taken time to bloom into 2017 and decide which direction and what you’re wanting to achieve as I was starting to feel it was only me that hadn’t decided everything by the 2nd Jan!! We were away in Cornwall until the 10th after a very hectic Christmas and just couldn’t get my head into gear at all….with lots of unfinished projects from 2016!!
    I would thoroughly recommend starting Vanessa’s Totem Class as it’s got me really thinking… just now how to get what’s in my head into my journal…good luck!

      I hear you Gill – so many great projects and directions to go in creatively and in life but sometimes you just get a bit overwhelmed with it all and what to do first! Cornwall sounds fantastic though – I’d love to go there and also Truro and Devon. I’ve read some lovely books set in that part of the country.

      I’ve got a family holiday to Florida starting tomorrow which will be a good time to relax and I’ve already bought the Totems class too – can’t wait to start. Something to look forward to in February which is also my birthday month :) xx
