The Rainbow
Forming a Rainbow
An observer sees red light coming from droplets of water higher in the sky, while droplets of water lower in the sky send violet light to the eye.
The Shape of the Rainbow
All of the droplets of water along the arc shown in the figure are equivalent. A rainbow would form a complete circle, not just an arc, if the ground didn’t get in the way.
Understanding Rainbow Geometry
Rainbow
Rainbows always face the observer. As the observer moves, the rainbow moves. One can never get to the “pot of gold” at the end of the rainbow.

The sight of over a hundred majestic horses galloping and shiny sublime stallions set the stage on fire. The sound of hoofs dominated the Woo’s and Boo’s from the crowd who had gathered to catch a glimpse of the courageous contenders challenging the soldiers of the Wellington Army School. Our high-octane contenders, the team from the Madras Riding School comprising Dhananjai Golla, Namrata Kishore, Hari Vishwanath, Arvind, Mouleeswaran Arulmani, Amritha Balu, Ishaan Saral, set out to jump those obstacles with utmost comfort and charm. They cast a spell so plausible that sent the crowd into frenzy.

Furthermore, setting a level playing field for the contestants, the contenders were classified into two categories, viz. Under 16 and Above 16. The tots endowed a scintillating performance. The members of the army school amazed the audience with their impeccable behavior and their identically behaved horses. Once the contestants had accomplished their mission they set out to achieve, it was moments of anxiety until the judges announced the results, considering the fact that other contestants being well-trained jockeys from Lovedale, Bangalore, Jabalpur, Coonoor, Ootacamund (Ooty) and other local riding schools.

If transcendent was the adjective, I would still call it an understatement. Three of our riders secured a place on the stands. Mouleeswaran Arulmani won the SILVER medal in the Accumalator Jump Event astride Fereneze in the above 16 years category. In the DRESSAGE event for children (10 – 12) Namrata Kishore won the SILVER medal astride Awesome Mover and the 4th place astride Star of Ring, Ishaan Saral won the BRONZE medal astride Awesome Mover.
The other medals were bagged by none other than the candidates of the Wellington Army School – A worthy opponent.

What is a Concave Lens
Lens that possesses at least one surface that curves inwards. It is a diverging lens, spreading out those light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia).
After light rays have passed through the lens, they appear to come from a point called the principal focus. The distance between the principle focus and the lens is the focal length. A more curved lens will have a smaller focal length and will be a more powerful lens. The image formed by a concave lens is virtual, upright, and smaller than the object, and it cannot be projected onto a screen. The lens formula is used to work out the position and nature of an image formed by a lens: 1/u + 1/v = 1/f, where u and v are the distances of the object and image from the lens, respectively, and f is the focal length of the lens.
