– Transmission of sound

– Types of sound waves

– Characteristics of sound waves

There are mainly three characteristics in sound waves; pitch, intensity and quality.

– Defining viscosity

– Newton’s formula

– Variation of viscosity with temperature

– Poiseuille’s formula

Viscosity is a measure of a fluids resistance to flow. When fluids moves slowly, its flow is orderly. If every fluids passing through a gives point follows the same line of the flow it is named as Laminar flow or stedy flow.

– Conditions that applied for standing

waves

Wave is a method of transmitting energy by means of large number of oscillations. Oscillations maybe mechanical or electromagnatic.

– Reflection

– Echoes

– Refraction

– Interference

– Beats

– Resonance

The general properties of sound waves are reflection, echo, refraction and diffraction.Also the properties based on superposition of waves are interference, beats and resonance.
