Red light has a wavelength of 70 A°. In "nm" it is
Answer & Solution
Correct Answer:
Option
A
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.
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.
