Question

The wavelength of a beam of light is 5894 A°.Express the value in nanometers

Answer 1

Answer:

589.4 × 10 to the power -9 nanometre

Answer 2

Answer:58940 nanometer

Explanation:

SO..1 A° = 10 to the power -10 meters

so,5894 A°=5894*10 to the power -10 meters

1 nanometer =10 to the power -9 meters

so,1 meter=10 to the power 9 nanometer

and 5894*10 to the power -10 meter=5894*10 to the power -10+9=5894*10 nanometer

or 5894A°=58940 nanometer
