6. The mean distance between the Earth and the Sun is 1.50 x 10 m. The average intensity ofsolar radiation incident on the upper atmosphcre of the Earth is 1390 W/m.Assuming thatthe Sun emits radiation uniformly in all directions, determine the total power radiated by theSun.7. An industrial laser is used to burn a hole through a piece of metal. The average intensity ofthe light is S -127 x 10" W/m". What is the rms value of the electric field? For thissame laser, what is the ms value of the magnetic field?8. A source of electromagnetic waves radiates power uniformly in all directions at a singlefrequency. At a distance of 3.50 km from the source, a detector measures the intensity of thewave to be 28.0 gW/m².a) What is the peak value of the magnetic field at the detector due to the wave?c) Now the detector is replaced with a perfectly absorbing sheet normal to the incidentlux, with surface area 1.50 m". What is the force on the sheet due to the wave?

The average Power radiated is given by P=IA Where I is intensity and A is area The rms value…
