Due to the reflection of light during the sun's light through the rain particles or water vapor-bladder, the channel is formed. In this spectrum, light is divided into colors. These seven stars are violet, blue, indigo, green, yellow, orange and red; In Bengali, the initials of these colors are summarized: VIIBGYOR in BeniAssala and in English, due to different color variations of these seven colors, they vary in size. Like the red color of the red color is curved at 42 ° angle. On the other hand, purple rays are curved in the 40 ° corners. Other color ranges are curved in different corners of 40 ° to 42 °. For this reason, the colors of the rainbow are seen in a certain row. The primary bright rainbow is a little subtractive, and the other is a secondary rainbow, in which the colors are inverted. The middle of the two arches (Dark Zone of Alexander) is a bit darker than the rest of the sky, but this variation can be avoided if not noticed properly.
Rainbow is not always seen. The time of the rainbow is rising, at that time the face of the sky changes. So those who have not seen the rainbow, of course it will be good to see.
