Question

A wave travelling in the +ve x-direction having displacement along y-direction as 1 m, wavelength 2π in and frequency of $\frac1{π}$Hz is represented by

• A. y = sin(x-2t)
• B. y= sin(2πx-2πt)
• C. y = sin(10πx - 20πt)
• D. y= sin(2πx + 2πt)

Answer 1

Answer: (A)

y = sin(x-2t)

Answer 2

The correct option is (A): y = sin(x-2t)
