Free webinar on Robotics (Block Chain) Learn to create a Robotic Device Using Arduino
30th Jan @ 5:00PM for Grade 1 to 10
The displacement associated with a wave is given by y(x,t)=0.1 cos(0.2x-2t) Where x and y are measured in centimeters and t in seconds, the frequency and the velocity are respectively The displacement associated with a wave is given by y(x,t)=0.1 cos(0.2x-2t)Where x and y are measured in centimeters and t in seconds, the frequency and the velocity arerespectively
The displacement of the wave is given by the equation given in the question.From this equation we can find that, k = 0.2 cm-1 and w = 2Wave velocity = coeffecient of t / coeffecient of x = 2 / 0.2 = 10 cm/sFrequency = w / 2 pi = 1/ pi s-1 where pi = 3.14 Hope it helps! Pls approve this answer if you found it useful.All the best!
