# The Wavelength of Light of a Particular Colour is 5800 å. (A) Express It in Nanometre - Physics

Sum

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

#### Solution

Wavelength of light of particular colour = 5800 Å

1Å = 10-1 nm

∴ 5800Å = 5800 × 10-1 nm

= 580 nm
