Reflecting telescopes can gather light from objects. This becomes basis the system to see Celestial objects.

Answer:
NaOBr (or) Na⁺ ⁻OBr
Explanation:
The Oxo-Acids of Bromine are as follow,
Hypobromous Acid = HOBr
Bromous Acid = HOBrO
Bromic Acid = HBrO₃
Perbromic Acid = HBrO₄
When these acids are converted to their conjugate bases their names are as follow,
Hypobromite = ⁻OBr
Bromite = ⁻OBrO
Bromate = ⁻OBrO₂
Perbromate = ⁻OBrO₃
According to rules, the positive part of ionic compound is named first and the negative part is named second. So, Sodium Hypobromite has a chemical formula of Na⁺ ⁻OBr or NaOBr.
