Between the primary and secondary rainbows, there is a dark band known as Alexander's dark band. This is because

Options

A. light scattered into this region interfere destructively
B. there is no light scattered into this region
C. light is absorbed in this region
D. angle made at the eye by the scattered rays with respect to the incident light of the sun lies between approximately `42^(@) and 50^(@)`

Explanation

**Step-by-Step Solution:**

1. **Understanding Rainbows**: Rainbows are formed due to the refraction, dispersion, and reflection of light in water droplets. The primary rainbow is formed by one internal reflection, while the secondary rainbow is formed by two internal reflections.

2. **Identifying Alexander's Dark Band**: Alexander's dark band is the dark region that appears between the primary and secondary rainbows. It is an area where there is significantly less light compared to the surrounding regions.

3. **Analyzing the Angles**: The angles at which the primary and secondary rainbows appear are crucial. The primary rainbow typically appears at angles between approximately 41 degrees and 43 degrees, while the secondary rainbow appears at angles between approximately 51 degrees and 54 degrees.
