Question | Answer |
---|---|
How would this representation look different if it had twice the frequency | There would be twice as many cycles(crest + trough) in the same space |
How would it look different if if had twice the amplitude | It would be twice as tall above and twice as deep below the at rest position |
In the space below, draw a representation of a longitudinal wave.Label the following:compression, rarefaction, wavelength, and amplitude | |
How would this representation look different if it had twice the amplitude | The compression would be twice as dense(more squished) |
A longitudinal wave can also be called a wave | Compressional |
The amplitude is related to the energy of the wave. If the energy of the wave increases, then the amplitude will be. A tsunami is an example of an high energy wave. | Larger |
For a transverse wave, the medium moves the energy of the wave.For a longitudinal wave, the medium moves in this case, the movement is in the form of vibrations, and the matter have a net forward motion | Perpendicular to, In the same direction as ,does not |
A wave does NOT have to have a medium, so it can actually travel through space. On the other hand, a wave must have a medium. It's velocity depends on the density of the medium, so it will have its greatest velocity in a medium. | Transverse,longitudinal, solid |
Waves with wavelengths like AM radio,diffract more easily | Longer |
Interference occurs when a crest of one wave overlaps a crest of another wave | Constructive,larger,destructive,larger |
The natural frequency of a vibrating string is 11 hz | 11hz 22hz antinode node |
Light waves, while sound waves are | Transverse,longitudinal |
