1.	The equation of a wave is given by y = 3sin(4x-2t). What is the time period and wavelength of the wave?(a) T = 2π, λ = 2π(b) T = π, λ = 2π(c) T = π, λ = π/2(d) T = π/2, λ = πThe question was asked during an interview.This interesting question is from Displacement Relation in a Progressive Wave in portion Waves of Physics – Class 11
Answer» Correct OPTION is (c) T = π, λ = π/2 The BEST I can explain: From the equation we GET: k=4 & w=2. Wavelength is GIVEN by 2π/k = 2π/4 = π/2. TIME period = 2π/w = 2π/2 = π.
