thermal equilibrium energy distribution for electromagnetic radiation (also called the “blackbody problem” because of the experimental apparatus). The quantity of interest was dr/df where r denotes the energy density and f the frequency (Fig. 1). No one had been able to derive dr/df from the first principles of statistical mechanics. One serious problem was in the high frequencies, which contributed infinite energy when one integrated over all frequencies to obtain the total energy! Planck thought

Activities Involved In the Conservation of Natural Resources Introduction The energy consumption of western cities' households stands at about one-third. Energy is a very good example of a natural resource. In as much as it is surprising, efforts have been made since the 21st century to try and conserve these natural resources (Montana Conservation Council, 1956, p. 12). The essay seeks to discuss how some of the activities carried out have been used to promote resource efficiency and sustainable

Module 3 Waves and the Electromagnetic Spectrum Topic: Waves 1. What is a wave? A wave is vibration that travels and all waves are created by something vibrating. Waves transport energy but do not transport mass. 2. Describe the following terms associated with waves: a. amplitude height of wave b. wavelength length of a wave c. frequency number of waves per second (Hz) d. period how long a wave lasts when it arrives at a fixed point (measured in seconds) 3. What are radio waves

DEMAND SIDE MANAGEMENT ENERGY EFFICIENCY & ENERGY CONSERVATION 5.0 INTRODUCTION Improving the efficiency with which energy is used to provide economic services meets the dual objectives of promoting sustainable development and of making the economy competitive. Energy Efficiency & Conservation has also assumed enhanced importance with a view to conserve depleting energy resources. Over the past one decade energy efficiency in India has been increasing at a good trot, and energy intensity declined

It is important to conserve energy especially when it is produced by non-renewable resources. We use non-renewable fuels to crank our cars, to hear our homes and to cool our homes. When pollutants from these non-renewable fuels are released into the air it contaminate the air we breathe along with the water that we drink. With that being said it is important to conserve energy to keep the air that we breathe cleaner. Conserving energy is also important because it reduces the electric bill and the
