1. The problem statement, all variables and given/known data A wave is represented by the wave function: y = A cos(2πx/λ + π/3) for x < 0. For x > 0, the wavelength is λ/2. By applying continuity conditions at x = 0, find the amplitude (in terms of A) and phase of the wave in the region x > 0. Sketch the wave, showing both x < 0 and x > 0. 2. Relevant equations y = A cos(2πx/λ + π/3) for x<0 and A cos(4πx/λ + φ) for x >0 3. The attempt at a solution I guess using the equation above we can make this. How to apply continuity condition and solve this? I have a little idea over this. can anyone please guide me through the entire question. Thank You.
