Answer:
The range of angles is from 17.50° to 31.76°
Explanation:
The diffraction grid equation is as follows:
Clearing for
where is the angle,
is the order, in this case
,
is the wavelength, and
is defined as follows:
and since the resolution is 750 lines/mm wich is the same as
will be:
wich is the distance between each line of the diffraction grating.
substituting the values for and
:
And we need to find two angle values: one for when the wavelength is 400nm and one for when it is 700 nm. So we will get the angle range
and
The range of angles is from 17.50° to 31.76°
