Draw the intensity pattern for single slit diffraction and double slit interference. Hence, state two differences between interference and diffraction patterns.
A) Both produce alternating bright and dark fringes.
B) Interference exhibits maxima and minima whereas diffraction only exhibits minima.
C) Interference involves the superposition of coherent waves from two or more sources while diffraction involves bending of waves around obstacles.
D) Both involve the spreading of light waves, but interference patterns have narrower fringes compared to diffraction patterns.
