The vibration regularity of particle and direction of wave travel are can be observable, and sometime, the relation between the direction of vibration of certain particle and direction of wave travel can be obtained by student oneself repetition test.
After the waveform in 3, certain moment known, waveform sometime after drawing out (such as: waveform after 1/2nd cycles, waveform etc. after 1/4th cycles).
Large bevel gear 5 rotates the complete waveform that a week just in time exports one-period, so carry out scale (0 ~ 2 π) on large bevel gear 5.First draw an oscillogram sometime, large bevel gear 5 can upwards lift, drawing paper or graph paper are moved on to origin-location (paintbrush 11 being placed on drawing paper or graph paper origin position), by the scale above large bevel gear 5 correspondence, turn over certain angle, draw again one with the sine curve of original the same length, this curve oscillogram sometime after being exactly Article 1 curve.If the oscillogram than after drawing for 1/4th cycles: first draw a sine curve, lift large bevel gear 5, drawing paper or graph paper are moved on to the position that Article 1 curve starts, adjustment large bevel gear 5 turns over an angle of 90 degrees degree, draw the curve of a same length again, this curve be exactly after oscillogram after 1/4th cycles.In like manner can draw, afterwards the oscillogram of any time.
4, the image that a particle does simple harmonic oscillation is drawn.
Draw a curve, make X-axis into time shaft, so image is exactly the image that certain particle does simple harmonic oscillation.
5, measure amplitude, wavelength, velocity of wave, cycle, phase place, frequency etc., amplitude, wavelength, velocity of wave, cycle, phase place, Pin Shuai Deng Zhuo adjustable.
Draw a sine curve, use stopwatch writing time, after drafting, measure its amplitude with ruler, the physical quantitys such as the distance of wavelength, propagation, then calculate its velocity of wave, the cycle simultaneously.Phase place, when starting, can be read by the scale on large bevel gear 5.
6, the principle of Doppler effect is demonstrated.
Adjustment rotating speed, makes it in same distance, can export more waveform, and then the origin cause of formation of Doppler effect is described.
7, electromagnetic Crack cause can be demonstrated.
Advantage: can draw not waveform in the same time continuously, movably can be quiet, is convenient to observe.
8, alternating current, voltage phenomenon is demonstrated.
