We can reasonably model a 75 W incandescent lightbulb as a sphere 7.0 cm in diameter. Typically, only about 5.0 % of the energy goes to visible light; the rest goes largely to nonvisible infrared radiation. Required:
a. What is the visible light intensity (in W/m^2) at the surface of the bulb?
b. What are the amplitudes of the electric and magnetic fields at this surface, for a sinusoidal wave with this intensity?

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0° north of east. the plane then flies to town b, located d2 = 230 km at 30.0° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)
