A wave has the form y = A cos(2πx/λ₀ + π/4) when x < 0. For x > 0, the wavelength is 5λ₀/7. By applying continuity conditions at x = 0, find the amplitude Ax > 0 (in terms of A) and phase ϕ of the wave in the region x > 0. ϕ = ?° Ax > 0 = ?A

Step 1
This means that the value of y at x = 0 must be the same for both the wave in the region x < 0 and the wave in the region x > 0. For the wave in the region x < 0, we can substitute x = 0 into the equation to find the value of y at x = 0: y = A cos(2π(0)/λ₀ + Show more…

A wave has the form $y=A \cos (2 \pi x / \lambda+\pi / 3)$ when $x<0 .$ For $x>0,$ the wavelength is $\lambda / 2 .$ 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 $x>0$.

Two waves are passing through a region in the same direction at the same time. If the equations of these waves are $$ \begin{aligned} &y_{1}=a \sin \frac{2 \pi}{\lambda}(v t-x) \\ &\text { and } y_{2}=b \sin \frac{2 \pi}{\lambda}[(v t-x)+x], \end{aligned} $$ then the amplitude of the resulting wave for $x_{o}=(\lambda / 2)$ is (a) $|a-b|$ (b) $a+b$ (c) $\sqrt{a^{2}+b^{2}}$ (d) $\sqrt{a^{2}+b^{2}+2 a b \cos x}$
Two sinusoidal waves of the same wavelength travel in the same direction along a stretched string. For wave $1, y_{m}=3.0 \mathrm{~mm}$ and $\phi=0$ for wave $2, y_{n=}=5.0 \mathrm{~mm}$ and $\phi=70^{\circ} .$ What are the (a) amplitude and (b) phase constant of the resultant wave?
