This is a well-described scientific story of light - well done Rakesh. Clearly, as your 'about me' section says: "you are a teacher"! Indeed you are!

Looking through your general writing I was 'taken' by your intense interest (and knowledge) of Indian Independence developments ... you obviously care about your country.

My wife is Indian - though I'm an English guy! We both now live in Australia.

One of my heroes is another 'freedom fighter' though he made a point of not fighting ... Mahatma Gandhi.

I've mentioned him in my Bio, and I'm just about to write an article about his views on Christianity, or, more accurately, his views on Christians, He had some great thoughts. When I've published it (soon I hope), you'll find it in my stories index etc. Not sure of its title yet, but am thinking of calling it "Mirror ..."

(now there's another connection with you 'light' article!). Look out for it.

Rakesh, I also wanted to say thank you for choosing to follow me. I have reciprocated.

I wish you well with your own writing.

May your day be just right for you … all the best to you and yours,

Fred
