What Is the Sunlight and Rainbow Chart Used For?
Sunlight looks white but is a mixture of colours. Passing through a glass prism, each colour bends by a slightly different amount — violet most, red least — so the beam opens out into a band called a spectrum, which Indian classrooms remember as VIBGYOR: violet, indigo, blue, green, yellow, orange and red. This splitting is dispersion. A rainbow is the same effect in nature. Sunlight enters a raindrop and bends, reflects off the back of the drop, and bends again as it leaves, so the colours separate and reach the eye from different drops. That is why a rainbow appears only when the Sun is behind you and rain is falling in front, most often after a shower in the morning or late afternoon, with red on the outside of the bow and violet on the inside; a fainter second bow, when there is one, has its colours reversed.
The ideas are taught formally in the NCERT class 10 science chapter on the human eye and the colourful world, which also explains why the sky is blue and why the Sun looks reddish at sunrise and sunset, and they appear earlier in primary and middle-school lessons on light. Teachers often pair the chart with a prism held in a sunbeam and a Newton’s colour disc, which looks almost white when it spins fast. The individual diagrams are not listed in the catalogue entry, so ask for a preview image if you need a particular topic, such as scattering, covered.
What to Specify When Ordering
- Number of charts — 10 units minimum.
- Demonstration items — a glass prism and a Newton’s colour disc let the class reproduce what the chart shows.
- Further light charts — the solar spectrum chart takes older students on to the dark lines in the Sun’s spectrum.
- Shipping details — destination, FOB or CIF terms for export, and any tender reference.
Frequently Asked Questions
Why does a prism split sunlight into colours?
Because each colour travels at a slightly different speed in glass and so bends by a different amount. Violet bends most and red least, which spreads the colours into a spectrum.
How is a rainbow formed?
Raindrops act like tiny prisms. Light is refracted as it enters a drop, reflected inside it and refracted again on the way out, separating the colours. You see the bow only with the Sun behind you and rain in front.
Why is the sky blue?
Air scatters blue light from the Sun far more strongly than red light, so blue reaches the eye from every part of the sky. At sunrise and sunset the light crosses much more air, the blue is scattered away, and the Sun looks red or orange.
What size is the chart and which languages does it use?
It is 50 x 75 cm and laminated, with English and Hindi on the same chart.
Is a prism included?
No. The listing covers the chart only. Glass prisms and Newton’s colour discs are separate products that can be quoted in the same enquiry.
