The velocity of a wave can also be defined as V=fλ, where V is the velocity of the wave, f and λ are the frequency and wavelength respectively. To verify this wave formula, The students set the wave to oscillate at a frequency of 2.2 Hz and then measured the distance between one crest to the other to be 9.1 cm.
How fast did the wave travel on the string? No need to include units in your final answer. Make sure all the measurements are in the S.I. units.
Suppose you take a 2.0×10^2ohm resistor and a 0.40 H inductor and make a series circuit with a voltage source that has voltage amplitude 30 V and an angular frequency of 2.5×102 rad/s. What are the voltage amplitudes across the resistor and across ..
