You are seeing a broad white pattern because the wide area of the grating is admitting too much light and your diffraction pattern is getting washed out by the broad background light. To make this ...

To separate white light into these colors, the light needs to pass through ... You can make your own spectroscope by following the instructions shown below! Assemble the diffraction grating end first.

For example, a series of thousands of scored lines in a glass plate diffracts light into a rainbow of colors. Lines of data pits on a CD give the same effect. See diffraction. THIS DEFINITION IS ...

Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of ...
