Question

The mean wavelength of yellow light from a sodium lamp is 5893 Armstrong. Write it in m and nm.

Answer 1

Explanation:

Express it in (i) metre (ii) nanometer. (i) As 1Å=1010m,∴λ=5893×1010m

Answer 2

Hi mate

1A°= 10^-10m

1nm =10^-9 m

In A° = 5893*10^-10m

In nm = 5893*10^-9 m

Hope it helps you...
