Photoelectric

The photoelectric effect occurs when light (or similar incident radiation, including X-rays) falls on material together with a metal plate and causes it to emit electrons. The discovery of the photoelectric effect led to important new theories (and to a Nobel Prize for Albert Einstein). Photoelectric cells, or photocells, are utilized in burglar-alarm light detectors and garage-door openers (each employs a through-beam of light this is broken when something movements throughout it), and also to play soundtracks on film movies (in which a light beam shines through the soundtrack encoded at the film and is "read" with the aid of the photocells).

Light consisting of two wavelengths, dg = 4.4 x 107 meter and ^, = 5.5 x 107 meter, is incident normally on a barrier with two slits
separated by a distance d. The intensity distribution is measured along a plane that is a distance L = 0.85 meter from the slits as shown
above. The movable detector contains a photoelectric cell whose position y is measured from the central maximum. The first-order
maximum for the longer wavelength A, occurs at y = 1.2 x 10² meter.
a) Determine the slit separation d.
b) At what position, y,, does the first-order maximum occur for the shorter wavelength ^ ?
c) In a lab setting, students replace the double slit with a diffraction grating of 300 lines/mm and place the viewing screen 0.50
m away. They replace the source of light with a laser of unknown wavelength. Using the photoelectric detector, they
determine the second-order maximum occurs at y = 4.5 x 10² m. Calculate the wavelength of the laser used.
