1-a 4 hz continuous wave travels on a slinky.
if the wavelength is 0.5m, what is the speed of waves on the slinky in ms-1?
2-a wave with oscillations perpendicular to the direction of propagation is called:
3-the only way to make sound travel faster in air is to change the air's
4-what is the rms of a signal with the waveform?
v(t) = 20.5 sin(4t)
5-what is the peak to peak amplitude (in volts) of a signal with the waveform
v(t) = 20.5 sin(4t)
6-the wavelength of a 40 000 hz ultrasound wave is measured to be 0.868cm.
find the air temperature (in oc)
