Question

A wave is represented by y = A sin 2 ⁡ k x - ω t + ϕ . The amplitude and wavelength of wave is given by, 2 A , 2 π k, A , 2 π k, A 2 , 2 π k, A 2 , π k

MARKS App · Accepted Answer

y = A sin 2 ⁡ k x - ω t + ϕ can be rewritten as y = A 2 - A 2 cos ⁡ 2 k x - 2 ω t + 2 ϕ Therefore the amplitude of the wave is A 2 and wavelength of wave is π k
