Q1091
Red light has a wavelength of 70 A°. In "nm" it is
A.
7 nm
AnswerB.
0.07 nm
C.
70 nm
D.
700 nm
Answer: Option A
Solution
Answer: Option A
Solution:
Angstroms (A°) to nanometers (nm) is:1 A° = 0.1 nm
So, to convert 70 A° to nanometers:
70 A° × 0.1 nm/A° = 7 nm
Therefore, the correct answer is Option A: 7 nm.
