why is the time meassured by the person T' and the one by the clock T? After alll the clock is what is moving and the person on the earth is still. I though what is moving is what T' is.The Hypersonic Technology Vehicle 2 (HTV-2) is an experimental rocket vehicle capable of traveling at 21,000k(m)/(h)(5830(m)/(s)). If an electronic clock in the HTV-2 measures a time interval of exactly 1-s duration, what would observers on Earth measure the time interval to be? Strategy Apply the time dilation formula to relate the proper time interval of the signal in HTV-2 to the time interval measured on the ground. Solution Identify the knowns: Delta au =1s;v=5830(m)/(s). Identify the unknown: Delta t. Express the answer as an equation: Delta t=gamma Delta au =(Delta au )/(sqrt(1-(v^(2))/(c^(2)))). Do the calculation. Use the expression for gamma to determine Delta t from Delta au : Delta t=(1s)/(sqrt(1-((5830(m)/(s))/(3.00 imes 10^(8)(m)/(s)))^(2))) =1.000000000189s =1s+1.89 imes 10^(-10)s The Hypersonic Technology Vehicle 2 (HTV-2) is an experimental rocket vehicle capable of traveling at 21,000 km/h (5830 m/s).

2) Consider a wave guide with a uniform cross section and perfectly conducting walls. The interior medium has permittivity $\epsilon_1$ and permeability $\mu_1$ for $z < 0$, and permittivity $\epsilon_2$ and permeability $\mu_2$ for $z > 0$. A propagating TM mode is incident from the left ($z < 0$). We therefore take $\begin{cases} E_0(e^{ik_1z} + Re^{-ik_1z})\psi(\vec{x}_\perp) & \text{for } z < 0, \\ E_0Te^{ik_2z}\psi(\vec{x}_\perp) & \text{for } z > 0, \end{cases}$ where $(\nabla_\perp^2 + \gamma^2)\psi(\vec{x}_\perp) = 0$ for some positive eigenvalue $\gamma^2$, and $R$ and $T$ are dimensionless coefficients. A time dependence of $e^{-i\omega t}$ is assumed. a) Find the allowed values of $k_1$ and $k_2$. b) Use the appropriate boundary conditions to compute the reflection amplitude $R$ and the transmission amplitude $T$.
