A regularlight Bulb Emits waves of various wavelengths (which makes the"white" light); The distribution of Intensities is a ContinuousFunction of the wavelength (as in the Discussion of Black BodyRadiation). This distribution, however, peaks at someCharacteristic wavelength. In the following Assume that the EntirePower of the Light Bulb comes from emitting in this SingleCharacteristic Wavelength. A light Bulb has aP=100W.
1.) Whatis the Intensity of the Emitted Light at a distance r = 10m fromthe Light Bulb?
2.) Whatis the Amplitude of the Electromagnetic Field atthat Distance?
3.) Whatis the Average Energy Density of the e.m.radiation at the distance r =10m from the light bulb?
4.) Whatis the momentum transferred by this light to asmall flat mirror with surface area S= 0.5m2 placed infront of the light bulb at the distance r = 10m during the timet=1s?
5.) Whatis the Pressure exerted by the light on theSurface from number 4?
