You and your friend Bruce are experimenting with a red lamp shade and blue lamp shade. You place lamp shades individually over a 120-W light bulb. Assume that the light radiates from the lamps uniformly and 9.5% of their power is converted to light. (a) What is the average intensity of the light at 1.6 m from the red (1 = 710 nm) lamp shade?

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:
