Write the mathematical representation of the wave graphed in the following two figures.
A transverse wave is represented by the following function: y=(18cm)sin[2π(2cmx−5st+41)]. What is the phase angle of this wave?
The function for some transverse wave is ? = (0.5 m) sin [(0.8 m−1)x − 2?(50 Hz)t + π/3]. What is the transverse velocity at t=2 s, x=7 cm? What is the maximum transverse speed? The maximum transverse acceleration?
