Description
Technical field
The utility model relates to a kind of experimental facilities, and especially a kind of enforcement is convenient, and perfect in shape and function, structure is simply applied to the experiment instrument of photoelectric effect simulation.
Background technology
Photoelectric effect is an important and phenomenon for mystery in physics.Higher than under the electromagnetic wave irradiation of certain characteristic frequency, the electrons of Cucumber inside is out formed electric current by photon excitation, i.e. photoproduction electricity.Photoelectricity is found in 1887 by roentgen hertz, and the correct einstein that is interpreted as proposed.Scientists is in the photoelectric process of research, and the quantum nature of physicist to photon has had more deep understanding, and this has significant impact to the proposition of wave-particle duality concept.
Teachers are in teaching process; student is presented in order to what can allow photoelectric effect science more more directly perceived; usually steel ball can be adopted to replace photon to simulate and to produce photoelectric detailed process; realize above-mentioned simulation process; usually following experiments article to be adopted: 3 steel balls; chute; books are some; the marking pen of red, orange, yellow, green, blue and purple; tables of data; and rule, concrete experimental procedure is as follows: chute is curved shape as shown in the figure, then with several books, chute supported is got up.Determine that books can not stop the terminal of chute.2., with on the chute at red symbol pen 4cm place on desktop, write a letter r (as figure), R represents red (Red).On chute with purple marking pen 14cm place on desktop, write an alphabetical V(as figure, V is a letter the most top on chute), V represents purple (Violet).On chute, blue B(and Blue is write respectively with other color mark pen, several 2nd letter from top to bottom), green G(and Green, several 3rd letter from top to bottom), yellow Y(and Yellow, several 4th letter from top to bottom,) and orange O(and Orange, several 5th letter from top to bottom), make them be uniformly distributed between R and V.3. two steel balls are placed on the minimum point of chute.These steel balls represent the valence electron of atom.4. get the position that a steel ball is placed on R on chute, this steel ball represents the photon of incident ruddiness.Note, red photons is that in simulated visible ray, energy is minimum.5. discharge steel ball (photon), if it has enough energy to remove a valence electron in atom, you can find that one of two steel balls (electronics) are escaped from from chute.Your observations is recorded in tables of data.
But although the step experiment arranged like this is got up more for convenience, but cannot well be controlled experimentation, such as steel ball because the uncertainty of motion, can drop in certain, makes people need in experimentation after ejection, steel ball will be caught simultaneously, cause certain inconvenience, more such as chute well cannot be fixed, also need artificial fixing, the structure of such instability not only can affect the accuracy of experimental data, also can bring more inconvenience.

As further improvement of the utility model, described steel ball accommodating component is the storage net be fixedly installed on fixed panel, and described storage net is resisted against steel ball segregation section, and is in same level with steel ball segregation section.
After have employed said structure, storage net is arranged at steel ball segregation section side, this net can be just in time fallen into when steel ball flies out, and receive size that the distance between net and steel ball segregation section nets in addition and will decide according to the distance after steel ball flies out, in all distances that the size of storage net also has the distance between steel ball segregation section steel ball must be flown out all are included in.
As further improvement of the utility model, described storage net comprises net and framework, and described framework is straight-flanked ring, described storage net is connected on this straight-flanked ring, described straight-flanked ring is semi-enclosed ring, and described straight-flanked ring opening part is provided with two tips, and described tip can insert in fixed panel.
After have employed said structure, being equipped with of framework and net, the shape of storage net can be made to be fixed, and the storage mouth of storage net is also larger, the steel ball facilitated each different distance flies out is received, material due to fixed panel is cardboard, so the tip setting inserted on cardboard also facilitates storage net to the connection between fixed panel, also facilitates the movement of storage net.
As further improvement of the utility model, described supporting component is the feet be arranged at bottom fixed panel, described feet comprises the first feet of the left and right sides be arranged at bottom fixed panel, described first feet is provided with second feet identical with its shape near fixed panel offside, described first feet and the second feet are equipped with threaded hole, be provided with stud in described threaded hole, the first feet and the second feet are fixed on fixed panel through fixed panel by described stud.
After have employed said structure, fixed panel can be vertically on surface level by arranging in pairs of feet, facilitates the demonstration of experimental result.And such feet not only structure is simple, and support effect is very good.
