Electromagnetic waves are radiated energy of all different strengths. They’re different from sound waves and water waves because they have the ability to travel through empty space. A vacuum. These are the only types of waves that do not need any type of medium because of photons. Photons are tiny particles that don’t get traveled through‚ but make up electromagnetic waves. Photons travel with the wave at about 300‚000 k/s. also known as the speed of light. The more energy the photons have‚ the brighter

sound waves Sound is a series of compression waves that moves through air or other materials. These sound waves are created by the vibration of an object‚ like a radio loudspeaker. The waves are detected when they cause a detector to vibrate. Your eardrum vibrates from sound waves to allow you to sense them. Sound has the standard characteristics of any waveform. Sound is a waveform that travels through matter. Although it is commonly in air‚ sound will rapidly travel

The short story "The Enormous Radio" written by John Cheever tells about a family‚ Jim and Irene Westcotts‚ who buys a new radio that permits them to eavesdrop on conversations and quarrels of other tenants of their apartment building. At first Westcotts appears like the perfect American family who seems to strike that satisfactory average of income‚ endeavor and respectability. They like listening to classical music and they went to a great many concerts. But they try not to show it off because

Characteristics and Nature of Waves In physics‚ a wave is a disturbance that travels through space and time‚ usually accompanied by the transfer of energy. Waves travel and the wave motion transfers energy from one point to another‚ often with no permanent displacement of the particles of the medium—that is‚ with little or no associated mass transport. They consist‚ instead‚ of oscillations or vibrations around almost fixed locations. For example‚ a cork on rippling water will bob up and down

BAND THEORY OF SOLIDS According to quantum free electron theory of metals‚ a electron in a metal experiences constant(or zero) potential and free to move inside the crystal but will not come out of the metal because an infinite potential exists at the surface. Bloch Theorem: According to this theorem‚ the periodic potentials due to the positive ions in metal have been considered. (i.e. the electrons moves in a periodic potential provided by lattice). If the electron moves through these ions‚
