At a certain geographic location, light intensity from the Sun is 900 J/(m² .s). This means that sunlight delivers 900 joules of energy to each square meter of ground in each second. Suppose solar panels are installed on the roof of a house to generate electricity from sunlight. The total area of the solar panels is 25 m². Calculate the maximum electric energy that can be generated per second: Unfortunately, solar panels are not 100% efficient at converting electromagnetic energy to electricity. Suppose the solar panels have an efficiency of 15%. This means that only 15% of the electromagnetic energy incident on the solar panels is converted to electricity, while the rest is reflected or converted to thermal energy. Given this efficiency, calculate the electric energy that can be generated per second:
wo radio waves are used in the operation of a cellular telephone. To receive a call, the phone detects the wave emitted at one frequency by the transmitter station or base unit. To send your message to the base unit, your phone emits its own wave at a different frequency. The difference between these two frequencies is fixed for all channels of cell phone operation. Suppose the wavelength of the wave emitted by the base unit is 0.34207 m and the wavelength of the wave emitted by the phone is 0.36677 m. Using a value of 2.9979 × 108 m/s for the speed of light, determine the difference between the two frequencies used in the operation of a cell phone. Give your answer to four significant figures.
