Question

Spacing of the diffraction grating

In the lab we will need to use the spacing d between lines on a diffraction grating. If the diffraction grating we use has 13400 grooves per inch how many groves per meter are there?

Number of grooves per meter =   [Num] [Units]

What is the spacing d between grooves (in SI units)?

d=  [Num] [Units]

Spacing of the diffraction grating

In the lab we will need to use the spacing d between lines on a diffraction grating. If the diffraction grating we use has 13400 grooves per inch how many groves per meter are there?

Number of grooves per meter =   [Num] [Units]

What is the spacing d between grooves (in SI units)?

d=  [Num] [Units]

Explanation / Answer

We know that, 1 inch= 0.0254 meter.

So, 13400 grooves per inch= 13400*39.37 grooves per meter= 527559  grooves per meter.

Hense,the relevent spacing based on the above would be the spacing d.
