Grating Orders

This simulation series is based on concept of Diffraction grating. A grating is a glass plate with many fine lines cut on it. The gaps between the lines act as thousands of narrow slits side by side. Waves from all the slits add in only a few sharp directions. Each colour gets its own angle.

What you'll learn

  1. Second order Light falls on a grating. Find the angle of the bright spot of a given order.
  2. Count the spots A curved screen catches every spot a grating throws. Find how many bright spots land on it.
  3. Colours overlap One order of a colour lands on an order of a second colour. Find the wavelength of the second colour.
  4. Missing orders The slits of a grating have a width. Find how many bright spots land on the screen.
