A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration, such as a ringing telephone, or a person’s vocal chords.

Here are some adjectives for sound waves: high-frequency, high-velocity, resultant exquisite, rhythmic, low-frequency, deep, full, high-frequency, supersonic, fat, heavy, low-frequency, high-velocity, ultrasonic, high-intensity, lightning-like, underwater, longitudinal, high-energy, inaudible, spherical, pent-up.

Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.

Sound is a mechanical energy which produces sensation of hearing. Sound is produced due to vibration of different objects. • Sound wave propagates as compressions & rarefactions in the medium. Sound waves are longitudinal waves.

Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed.

• Wavelength. Source: www.sites.google.com.
• Amplitude.
• Time-Period.
• Frequency.
• Velocity of Wave (Speed of Wave)

The basic properties of sound are: pitch, loudness and tone. Figure 10.2: Pitch and loudness of sound. Sound B has a lower pitch (lower frequency) than Sound A and is softer (smaller amplitude) than Sound C. The frequency of a sound wave is what your ear understands as pitch.

Sound vibrations travel in a wave pattern, and we call these vibrations sound waves. Sound waves move by vibrating objects and these objects vibrate other surrounding objects, carrying the sound along. Sound can move through the air, water, or solids, as long as there are particles to bounce off of.

Waves are disturbances that travel through a fluid medium. Several common wave characteristics include frequency, period, wavelength, and amplitude.

The higher the amplitude, the higher the energy. To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.

The killing and destructive power of electromagnetic radiation can be used constructively for curing the incurable diseases by eradicating the disease producing pathogens and micro organisms like bacteria, virus & fungi.

Radio waves are used for communications and radar. Microwaves are used to cook your food. Infrared waves are used in remote controls and are emitted from all warm objects, allowing them to be used to create heat-sensitive cameras.

Typical materials used for electromagnetic shielding include sheet metal, metal screen, and metal foam. Common sheet metals for shielding include copper, brass, nickel, silver, steel, and tin.
