The questions from today’s “January 9, 2026” on NYT Mini Crossword are a little bit brain teaser. Many people are looking for an answer to it. Here we are sharing answers for clues.
Clue: The “U” of UV rays
Answer: ULTRA
Explanation of clue:
The clue “The ‘U’ of UV rays” points to the word “ULTRA,” which is a part of the term “ultraviolet.” UV rays refer to ultraviolet radiation, a type of energy emitted by the sun and artificial sources like tanning beds. The term “ultraviolet” is derived from the Latin words “ultra,” meaning “beyond,” and “violet,” which is the color of the shortest wavelength of visible light. Ultraviolet light has wavelengths shorter than visible light, thus positioning it beyond the violet end of the spectrum. This understanding of UV radiation is crucial in various fields such as dermatology, where it is known for its effects on skin health, and in environmental science, where it plays a role in ozone layer studies. The emphasis on “ULTRA” in this context underscores the prefix’s meaning of exceeding or going beyond, which is fitting since ultraviolet rays extend beyond the visible spectrum.
