Questions & Step-by-Step Solutions

What is the effect of increasing the wavelength of light in a diffraction grating experiment?
  • Step 1: Understand what a diffraction grating is. It is a tool that spreads light into its different colors (wavelengths).
  • Step 2: Know that light can have different wavelengths. Wavelength is the distance between two peaks of a wave.
  • Step 3: When light passes through a diffraction grating, it creates patterns of light and dark areas called fringes.
  • Step 4: The distance between these fringes is called fringe spacing.
  • Step 5: If you increase the wavelength of the light (make it longer), the fringe spacing also increases (the fringes spread out more).
  • Step 6: This means that with longer wavelengths, you will see the fringes farther apart from each other.
