What is the name given to the noticeably darker region of sky that appears between a rainbow's primary and secondary bows?
Alexander's dark band—the sky between primary and secondary rainbows—is noticeably darker because light undergoes an extra internal reflection, canceling brightness.
Which color of visible light bends at the sharpest angle when refracted by raindrops to form a rainbow?
Red appears on the outside of rainbows and violet inside—yet violet light bends more sharply than red, creating a counterintuitive display.
In a primary rainbow, which color appears on the outermost edge of the arc?
Red appears on the outside of rainbows and violet inside—yet violet light bends more sharply than red, creating a counterintuitive display.
Why did Rosalind Franklin never receive a Nobel Prize for her role in uncovering DNA's structure, despite her critical X-ray data?
Franklin died of ovarian cancer at 37, four years before the Nobel Prize was awarded; the prize cannot be awarded posthumously, so she never received recognition.
Which scientist's unpublished X-ray diffraction images, shared by Maurice Wilkins, proved crucial to Watson and Crick's DNA model but sparked decades of controversy over credit?
Maurice Wilkins, who shared the Nobel Prize, initially resented Watson and Crick's credit, and his role in providing Franklin's data remained contentious for decades afterward.
In Linus Pauling's flawed 1953 DNA model, where did he place the sugar-phosphate backbone?
Linus Pauling, a Nobel laureate, proposed an entirely wrong triple-helix DNA model with phosphates inside—partly because he lacked access to Franklin's crucial X-ray data.
