Questions & Step-by-Step Solutions

What is the effect of increasing the wavelength of light on the diffraction pattern produced by a single slit?
  • Step 1: Understand what diffraction is. Diffraction is the bending of light waves when they pass through a narrow opening, like a slit.
  • Step 2: Know what wavelength means. Wavelength is the distance between two peaks of a wave. Longer wavelengths mean the waves are more spread out.
  • Step 3: Recognize that when you increase the wavelength of light, the waves become longer and more spread out.
  • Step 4: Realize that a broader wavelength causes the light waves to spread out more after passing through the slit.
  • Step 5: Conclude that as the wavelength increases, the diffraction pattern (the pattern of light and dark areas) becomes wider or broader.
