The position of rainbows depends on the some factors like wavelength of light and position of sun. So, it can occur at the horizon or above the horizon at the 40 - 42 Degrees. Hence, option (A) and (C) are correct.
The given problem is based on the concepts and fundamentals of Rainbow. The rainbow is the band of seven of seven colors namely, violet, indigo, blue, green, yellow, orange and red.
- Rainbows are caused by the sunlight and always appears in the section of sky, directly opposite to the sun.
- The position of rainbow depends on the wavelength of light such that the light leaves the collection of water droplets (or raindrops) to extend and angle in front of the observer. (Generally between 40 - 42 Degrees).
- But in many general cases, the rainbows occurs when the sun is exactly on the horizon and most of the time we can only observe the smaller segment of an arc.
Thus, we can conclude that the position of rainbows depends on the some factors like wavelength of light and position of sun. So, it can occur at the horizon or above the horizon at the 40 - 42 Degrees. Hence, option (A) and (C) are correct.
