Question

Write the following numbers in decimal form. (Note: Some of these numbers have been rounded.)

The wavelength of light used in optic fibers is 1.55 × 10^−6 m.

Answer 1

So wavelength in decimal can be written as 0.00000155 m

Explanation:

We have given wavelength of light used in optic fibers is
`1.55* 10^(-6)m`

We have to convert this wavelength in decimal form

We know that
`10^(-6)` can be written as
`10^(-6)=(1)/(1000000)=0.000001`

So
`1.55* 10^(-6)=1.55* 0.000001=0.00000155m`

So wavelength in decimal can be written as 0.00000155 m
