Question

The wavelength of light of a particular colour is 5800 Å.
Express it in nanometre.

Answer 1

As we know, 1 nm = 10 Å

Given, Wavelength of light of particular colour = 5800 Å

Substituting the value of wavelength in the relation above, we get,

10 Å = 1 nm

1 Å = `1/10` nm

∴ 5800 Å = `1/10` × 5800 nm

∴ 5800 Å = 580 nm

Hence, wavelength of 5800 Å in nm = 580 nm.
