The theme for this week’s Weekly Photo Challenge is ‘Refraction’. Over at the Daily Post, Kevin asks:
‘For this photo challenge, show us what “refraction” means to you. It could be an image taken in a reflective surface, it could be light bent from behind an object, or it could mean remedial math homework: the choice is completely up to you. I’m looking forward to seeing how you interpret “refraction.”’
Not being too clear on the exact meaning of ‘refraction’ as opposed to ‘reflection’, I came across ‘wiseGeek‘, a website described as having ‘clear answers for common questions‘. My kind of website in other words.
It defines ‘refraction’ as:
‘… the bending of waves as they pass from one medium to another, due to a change in their speed. The phenomenon is most commonly associated with light, but can also apply to sound, or even water, waves.’
A rainbow captures this as a perfect example. Sunlight has different wavelengths of colour (for instance, blue has a shorter wavelength than red) which ‘bend’ when they pass through raindrops. The different colours are split, so creating a beautiful rainbow:
In ‘Duck on Bridge’ as I like to call it (I wonder why), another example of refraction, I think, is the image of the bridge captured in the reflective surface of the water:
Sunlight catches the reflection of this glorious rhododendron celebrating an early summer as it dances on the waters of this tiny inlet:
The way sunlight refracts through the water here makes me think of melting glass:
Or maybe it could just be the way sunlight slices through the blinds in this window, warming my cats:
I may not have captured ‘refraction’ correctly in some of these photos, but I hope you enjoyed them anyway.
Happy Thursday everyone 🙂
