Question

mericals :
of a particular colour is
netre and (b) metre.
The wavelength of light of a particula
5800 Å. Express it in (a) nanometre and (b)
Ans.(a) 580 nm, (b) 5.8 x 10-7
​

Answer 1

Firstly ur question is not clear.

But that i have understood,

The wavelength of light in angstrom is 5800 A

Its wavelength in metre is:-

1 A = 1/10 m

5800 A = 5800*1/10 m

=580 nanometre.
