Wavelength of Hg Source Using Plane Diffraction Grating

Product Description


To determine the wavelength of any three lines of mercury light by diffraction grating in 1st and 2nd order spectrum.



Base : painted base with 3 leveling screws.

Scale : circular scale is graduated 360' in half degrees & is attached to the arm with telescope ,so that it moves when telescope is moved.

Vernier : 30 or 60 divisions of Vernier coincide with 29 (or 59) divisions of the main circular divisions.

Collimator : This horizontal tube has an achromatic lens( 7” F.L.) at one end and a sliding tube with on adjustable vertical slit at the other. The distance between the lens & slit can be changed by a rack & pinion for obtaining parallel rays.

Slit : consists of two sharp edges; one fixed while the other can be moved by a screw provided.

Telescope : it is an astronomical telescope with an achromatic objective of 7” F.L. And a Ramsden's eye piece.

Prism Table : two circular plates separated by 3 springs having leveling screws. Its height can be adjusted by a screw on its side. On its top a grating holder & prism holder is mounted.

Vernier : 60/30sec.
