Question

What is the wavelwngth difference between the two lines of sodium?

Answer 1

Sodium has two emission wavelengths that are extremely close in wavelength and without sensitive equipment cannot be distinguished. These lines, designated the D2 and D1 Fraunhofer lines, have wavelengths of 589.6 nm and 589.0nm respectively1.
