Two waves travel simultaneously through the same medium. The first wave is described by y₁(x,t) = (2.00 cm)cos[kx-ωt] and the second wave by y₂(x,t) = (3.00 cm)sin(kx-ωt). What is the amplitude of the resulting wave? A)1.00 cm B)2.50 cm C)3.61 cm D)5.00 cm E)3.94 cm

Question

Quizplus · Accepted Answer

The amplitude of the resulting wave is found using the Pythagorean theorem for the amplitudes of the two perpendicular waves: √((2.00 cm)² + (3.00 cm)²) = 3.61 cm.
