Questions & Step-by-Step Solutions

What is the relationship between the slit width and the angle of diffraction in a single-slit experiment?
  • Step 1: Understand what a single-slit experiment is. It involves shining light through a narrow slit and observing the pattern created on a screen.
  • Step 2: Identify the slit width. This is how wide the opening of the slit is.
  • Step 3: Learn about diffraction. This is the bending of light waves when they pass through the slit.
  • Step 4: Recognize that the angle of diffraction is the angle at which the light spreads out after passing through the slit.
  • Step 5: Note the relationship: as the slit width gets smaller (narrower), the angle of diffraction gets larger (wider spread of light).
  • Step 6: Conclude that the angle of diffraction is inversely proportional to the slit width: smaller slit width means larger angle of diffraction.
