- When flight controllers on Earth spoke to Apollo astronauts on the Moon, there was a noticeable time delay in the communications How long does it take a radio signal to travel to the Moon and back?Calculate the frequency of an EM wave if the wavelength is 2mCalculate the wavelength of a 2 MHz frequency EM wave in km, m, cm, mm and nm.
- In situations where a small signal must travel over a distance,a shielded cable is used in which the signal wire is surrounded by an insulator and then enclosed by a cylindricalconductor (shield) carrying the return current. Why is a“shield” necessary?What is the frequency of an EM wave that has a wavelength of 1667.58 m? Round your answer to two decimal places.On its highest power setting, a certain microwave oven projects 1.00 kW of microwaves onto a 30.0 by 40.0 cm area. What is the peak magnetic fieldstrength B0 ?
- Under what conditions might wires in a circuit where the current flows in only one direction emit electromagnetic waves (select all that apply)? When the current as a function of time is described by the function I(t) = 6.0 A When the current is switching between two distinct positive values When the current has any nonzero constant value When the current passes through a resistorAn MRI machine needs to detect signals that oscillate at very high frequencies. It does so with an LCLC circuit containing a 15 mHmH coil. To what value should the capacitance be set to detect a 370 MHzMHz signal?The wavelength of an electromagnetic wave is measured to be 1.60 x 10-7 m.
