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

Answer:

$535\times 10^{- 9} nm$

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 $\mu m = 1\times 10^{- 6} m$

Thus

$\lambda = 0.535 \mu m$

Also, we know that

1 nano meter or 1 nm = $0.535\times 10^{- 9} m$

Thus

Wavelength in nanometer is, $535\times 10^{- 9} m$
