Portion of Electromagnetic Spectrum Related to Earth and Space Sciences

Two editions. The 2024 edition of the Reference Tables was used for the June 2025 through August 2026 Regents examinations, and the past questions on this site were written for it. The 2026 Revised edition applies from the January 2027 exam onward, so a student preparing for January 2027 or later should practise with the 2026 Revised edition.

This site does not copy the reference tables. Open them on the NYSED website with the links below.
