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

`535* 10^(- 9) nm`

Solution:

The wavelength of the light source is represented by '
`\lambda`'

Here, the wavelength of the source of light is given as 0.535
`\mu m`

We know that 1 micro meter or 1
`\mu m = 1* 10^(- 6) m`

Thus

`\lambda = 0.535 \mu m`

Also, we know that

1 nano meter or 1 nm =
`0.535* 10^(- 9) m`

Thus

Wavelength in nanometer is,
`535* 10^(- 9) m`
