1. Define wavelength. How is it related to the phase constant?
2. What is the relationship between frequency, wavelength, and phase velocity? What is the wavelength in free space for a frequency of 15 MHz?
3. What is the direction of propagation for a uniform plane wave having its electric field in the negative y-direction and its magnetic field in the positive z-direction?
To avoid changing amplitude scales onthe oscilloscope during the demonstration, suppose that you wantthe resistor voltage (in both circuits), the capacitor voltage, andthe inductor voltage to have the same magnitude. Find the required relationship..
A series circuit has a voltage supply of 6 V and a resistor of 2.0 kΩ. What is the amount of power dissipated by the resistor? What is the voltage across the capacitor after the switch is closed and the capacitor is fully charged?
