Dispersion Grating: Wavelength range and resolution
Measure (and estimate or checked with a model) the relationship between the source slit width and the spectral resolution (in nm) of a diffraction grating.
Goals of Week 4 should also include:
(i) Measure the input and output angles of the diffracted light
(ii) Verify your results with the diffraction equation
(iii) Further verify your results by using a laser pointer
(iv) Estimate the ideal-case wavelength resolution for a given slit width at your experimental condition
According to https://www.answers.com/Q/What_is_the_track_pitch_or_groove_spacing_on_a_CD_DVD_or_Blu-ray#ixzz1noOSlNQ3
http://wiki.answers.com/Q/What_is_the_track_pitch_or_groove_spacing_on_a_CD_DVD_or_Blu-ray#ixzz1noOSlNQ3
The groove spacing is also called the "track pitch". It is the distance between each track. Here is a list of the track pitches of some common formats.
CD 1.6 ∓0.1 μm
DVD 0.74 μm
Blu-ray Disc 0.32 μm |
