A transverse wave is described by the expression y= 0.05cos(4.19x-1260t). You may assume all measurements are in the correct SI units. A) What is the amplitude of this wave? B) What is the wavelength of this wave? C) How fast is the wave travelling? D) What is the maximum tranverse velocity of the wave? Relevant equations: y= a sin (b(x-c)) +d Lamda= velocity/frequency Velocity= delta x/ time A) the amplitude is 0.05 as "a" in the formula is always amplitude. I am having trouble figuring out the last three questions but. How you do figure out the wavelength? Do you have to draw the wave on a quadrant graph and get the information off that?
