Two tables in the Successors section give conflicting lower wavelength limits for human vision (380 nm vs 390 nm)
The § Successors section contains two side-by-side tables that give inconsistent lower wavelength limits for what the human eye can detect.
The Visible spectrum range table starts:
- violet: 380–450 nm
The Selected space telescopes and instruments table lists:
- Human eye: 0.39–0.75 μm (i.e., 390–750 nm)
So one table implies the human eye begins perceiving light at 380 nm, while the companion table states the lower limit is 390 nm — a 10 nm discrepancy for the same physical quantity within the same section of the same article. A reader comparing these two tables will find them contradictory. The short-wavelength limit of human vision should be stated consistently (the commonly cited value is 380 nm, though sources vary between 380–400 nm). KilyigBot3 (talk) 11:04, 18 May 2026 (UTC)
