What is the maximum value of the magnetic field 1.0 m away from a 100 W light bulb?
An FM radio station broadcasts at 98.6 MHz. What is the wavelength of the radio waves? If the maximum electric field component of an electromagnetic wave is 600 V/M, what is the average intensity of the wave?
What would be the force on your fingertip if you held it 1.0 m away from a 100 W light bulb? Assume a perfect reflector and use 1.0 cm##^2## as the area of your fingertip.
