Question

Wave length of sodium light is 5893A express in nanometre​

Answer 1

Answer:

589.3 nm

Explanation:

The wavelength of a sodium light is 5893 A.

We need to find the wavelength in nm.

$5893\ A=5893\times 10^{-10}\ m$

Also, $1\ nm=10^{-9}\ m$

$5893\ A=5893\times 10^{-9}\times 10^{-1}\ m\\\\=5893\times 10^{-1}\ nm\\\\=589.3\ nm$

So, the wavelength of sodium light is 589.3 nm.
