Question

the wavelength of a certain light source is "0.535" where 1 micrometer = 1.0 x 10^-6m. express this wavelentg in nanometers.

Answer 1

The answer is 535 nanometers.

Step-by-step explanation:

`1\ micrometer = 1\ \mu m = 1.0* 10^(-6)\ m.`

and

`1\ nanometer = 1\ nm = 1.0* 10^(-9)\ m.`,

so

`1\ \mu m = 1.0 * 10^(3)\ nm`

which means that

`\lambda = 0.535\ \mu m = 535\ nm`.

In fact we can say that the light is green, because its wavelength is in the range of 500 nm to 565 nm.
