Interactive Simulations for Teaching Physics
Diffraction Grating
Authors: Ms. Giselle dos Santos Castro - Federal University of Ceara - UFC
Dr. Nildo Loiola Dias - Federal University of Ceara - UFC
CONTROLS:
- Choose the light color (wavelength) from 3 possibilities.
- Choose a diffraction grating from three possibilities.
- Adjust the distance between the diffraction grating and the screen on the available cursor.
- Click the SHOW RULER button to get a ruler that can be moved to the desired position.
DESCRIPTION OF THE SIMULATION:
This simulation makes it possible to study the diffraction of light in diffraction gratings. There are three wavelengths (colors) to choose from, a diffraction grating with 80 lines/mm allows you to determine the wavelengths. There are two diffraction gratings whose number of lines/mm is unknown. A cursor allows you to vary the distance between the diffraction grating and the screen. The diffraction pattern generated on the screen can be visualized. A ruler allows you to measure the necessary distances.
For an analysis of the data, consult one of the proposed ACTIVITY GUIDE.
