Question

Name Problem 4 Two waves, one with wave function D0.250 sin(2.27x 16.71), and another with wave function D2 = 0.250 sin(2.27x + 16.70, interfere to form a wave with displacement D = Di D2-Note that aff values are in SI (mks) units and angles are in radians. (5 Points) a) Write the wave function for the combined wave D. What type of wave is formed and what is the maximum amplitude of the combined wave D? (5 Points) b) What is the x position of the first node in the range>0? c) What is the x position of the first antinode in the range x>0? d) If the waves are on a string attached at both ends and the frequency represents the third harmonic (n 3), what is the length of the string? e) If the first wave function is now D 0.250 sin(2.270x + 18.7t), with the wave remaining the same, what is the beat frequency (in Hz) of the resultant wave? (5 Points) (5 Points) (5 Points)

Can someone explain why for part b when I solve for the wavelength instead of 0.28 i get 2.81(im doing 2pi/k and have no clue why the answer is 0.28)
