_____________________________

Value = 6400 Å

To convert Angstrom into Micron,

1 Å = 0.0001 micron

∴ 6400 Å

= 6400/1000 micron

= 0.64 micron

To convert Angstrom into Metre,

1 Å = 1 × 10–¹⁰ metre

∴ 6400 Å

= 6400/1×10–¹⁰

= 6.4 × 10–⁷ metre

$As 1Å = {10}^{2} m$

∴ Wavelength of light=64000Å

$= 6400 \times {10}^{ - 10} m$

$= 6.4 \times {10}^{ - 7} m$

Also,

$1micron = {10}^{ - 6} meter$

∴ Wavelength of light (in micron)

$= \frac{6.4 \times {10}^{ - 7} }{ {10}^{ - 6} } micron$

=0.64 micron
