Electrons pass through a 250-nm-diameter circular aperture, forming a diffraction pattern on a detector 1.2 m behind the aperture. What is the kinetic energy of the electrons if the width of the central maximum is 0.37 mm?

Draw a labelled sketch showing how the eye works and which parts of the eye see variations of contrast, color and detail (include rods and cones in your sketch). What does the “blind spot” mean and where is it in the eye? Does the eye see an upright or an inverted image? How does the lens of the eye work? Is the lens static?

Problem 2. In diffraction experiments involving multiple wavelengths of light passing through the same aperture, the higher order maxima of one wavelength can coincide with a lower order maxima of a longer wavelength. In the above diffraction experiment, the 3rd maxima of 600 nm light is found to coincide with the 4th maxima of a different wavelength of light. What is the other wavelength?
