Question

The wavelength of light of a colour is 6000 Å. Express it in nanometers and metres.

Answer 1

Answer:

The wavelength of light of a colour = 6000A

In metres it is expressed as

$= 6000 \times 10 {}^{ - 10} m$

In nanometer it is expressed as

$= 6000 \times 10 {}^{ - 9} nm$

Answer 2

600 nm and 6 * 10^-7 m

Explanation:

The wavelength of light of a colour is 6000 Å.

1 nanometer = 10 Angstrom, so 6000 Angstrom = 6000 / 10 nanometers = 600 nanometers

1 meter = 1 * 10^10 Angstrom, so 6000 Angstrom = 6000 / 10^10 meters = 6 * 10^(+3-7) meters = 6 * 10^-7 meters
