Biologists at the University of Massachusetts Amherst have released the first broad-scale, comparative, fine-grained analysis ...

There was a general tendency for them to increase their volume when they were whistling at a lower frequency. But aside from that, there were no clear amplitude patterns across dolphins or within ...

A calibrated microphone is placed in front of the speaker and feeds the speaker’s output into a machine that plots the frequency vs. amplitude as shown in Figure A. Figure A Now take a look at the ...

Save guides, add subjects and pick up where you left off with your BBC account. f = frequency = number of waves produced by a source per second, in hertz Hz. T = period = time it takes for one ...

Figure 3 Tout amplitude versus R3, 0 = Fully CCW, 1 = CW. Note that R3 has no effect on Pout or –Pout amplitudes, which always have full Vss to Vdd excursions. Oscillation frequency is affected by ...

Save guides, add subjects and pick up where you left off with your BBC account. A boat at sea bobs up and down as waves pass. The vertical distance between a crest and a trough is 52 cm and 20 ...
