2. The distance I in mask E is one half of the distance I of the sine wave in mask D, but the two waves have the same amplitude. Predict how the diffraction pattern from mask E will differ from that of mask D. Record the diffraction pattern from mask E and resolve any discrepancies with your predict tion. (Hint: re-sketch the sine wave figure, except make d half as big while keeping the amplitude the same and then sketch the resulting diffraction pattern)
