A, choice:(60%)
1.()The light wave belong to Wu primary wave secondary wave to maneuver wave above all not.
2.()Wave glint at present row describe He2 Xiang4 mistake flap certain ratio go into shoot a big frequency must constant wave-length must constant angle of incidence etc. Wu glint Cape.
3.()The wave-length velocity of the energy period flapped a decision Wu that undulate.
4.()The voice is in followingly what object the most quick quartz hydrogen water of the dissemination velocity air.
5.()The sound fork"vibrate every second of number of times" be called a period frequency: that flap of sound fork to put.
6.()Some frequency of one motion is 10 Hes, this motion then vibrates within a second 10100100010000 times.
7.()The energy deliver by motion with flap the direct proportion flap a square the direct proportion flap the inverse ratio flap a square inverse ratio.
8.()Lie a quality top and bottom or or so vibrate once, the form of the wave then goes forward one 234 wave-lengths.
9.()Measure the sound fork vibration frequency is a 50 Hzs, then its vibration period is 500.050.0220.
10.()Be to there is ripples of water spread, the defoliation which floats a Wu surface will go to in the original place to up and down vibrate to hold still above with the wave all not.
11.()Person's ear can recognize orotund frequency scope to invite from 20 Hes to 2002000200008000 Hes.
12.()The reciprocal of frequency be called to flap a period wave-length to round to shoot.
13.()V=331+0.6 ts, among them, the t mean the temperature frequency of thickness Celsius in time.
14.()The secondary wave is again called the Shu airtight wave or so wave to round to shoot a Gao Di Po.
15.()Gao Di of the tone from flap to synthesize a frequency wave-length to decide.
Two, fill:(30%)
(1)A certain be subjected to interference in the object, but this perturbation to elsewhere deliver of the phenomenon be called.
(2)Lie the direction for go forward of direction and wave of quality vibration mutual perpendicular of the motion be called.
(3)Try to raise two kinds of mechanics wave: , .
(4)The motion meets stumbling block but return of the phenomenon be called.
(5)The wave soon waits a Wu wave-length to multiply.
