Medicine for a Rainy Day

On a dreary, rainy autumn day, Cee’s photo challenge for vibrant colors is just what the doctor ordered!

Goldfinches love to eat the seeds from these thistles (I believe they are Canada thistles). While the thistles are highly invasive and very much disliked by most gardeners, I will leave just a few of them around because butterflies and birds really like the blooms and seeds. And the purple blossoms are cheerful to look at (for this human).

Reflection on Refraction

This week’s photo challenge theme is Refraction.

I wasn’t entirely sure how refraction differed from reflection. A quick consult with Webster’s Dictionary told me that refraction is about the bending of a ray or wave of light (or heat or sound) as it passes through a medium such as water. It showed the image of a drinking straw in a glass of water. At the point where the straw touches the water, it appears that it got cut and moved sideways a bit under water – an illusion caused by the bending of light by water.

This picture shows how a tiny water drop ever so slightly distorts (displaces) the ribs of the leaf:

I am pretty certain, that this nested reflection in these water glasses qualifies as a refraction:

Also, the distortions caused in round reflective objects seem like refractions to me rather than simple reflections:

Some windows will yield reflections almost like a mirror, but not this one:

The adjective “refractory” refers to being altered, hard to manage, stubborn, not yielding to treatment, resistant to heat. I am beginning to like this word….

So the difference between reflection and refraction? In my mind (and I am not a physicist), reflection is a simple mirror image on water or another reflective surface while refraction breaks up the image. I am wondering whether reflections on a disturbed (not smooth) water surface would be considered refraction? Like here, where the carp on the right has broken the water’s surface and rippled it so that the image of the fish is no longer as clearly defined as the one on the left?

Autumn Moods

Heavy rain clouds alternating with bursts of sunlight created many different moods this evening.

The orange golden flames of maple trees light up the landscape

I follow this winding country road

savoring the play of light on the canvas laid out before me

As the clouds swallow the sun,

tree and fence

they cast a purple hue across the land.

A final glimpse of sunlight on the mountain, then evening descends.

Dreamy Cat

When cats doze lazily
in the languid afternoon sun,

do they dream?
