Question

The wavelength of D1 line of sodium is 589.6 nm express it in A unit​

Answer 1

Explanation:

1nm = 10^-9 m

1 Angstrom = 10^-10 m

589.6nm = 586.9 × 10^-9 m

we will shift one decimal to the right

= 5896 Angstrom

Answer 2

1nm = 10^-9 m

1 Angstrom = 10^-10 m

589.6nm = 586.9 × 10^-9 m

we will shift one decimal to the right

= 5896 Angstrom
