Typed 1 What is the Virginia Johnson; Sound travels in waves, Teach Long and Short Vowel Sounds. This one is mainly based on a person's perception.

But the decibel scale is an exponential one so it depends from how loud you are starting from. This is mainly used on pregnant women as the waves do not harm the unborn child or mother, as technically it is just vibrations then detecting the returning signals. Some people use them as sleeping aids.

We can find the velocity of sound using resonance phenomenon with resonating air-column experiment. There are several examples of transverse waves in everyday life. Amplitude- The maximum vertical displacement of the medium particles on either side of its equilibrium position is called as the amplitude.
Frequency- The number of oscillations made by a medium particles in 1 second is called as frequency of wave. Wavelength- The distance travelled by the mechanical wave in one complete vibration is called as wavelength of wave. Sine wave- These waves repeat oscillations following sine equation. This wave pattern can be seen in ocean waves and light waves.
Square wave- this wave pattern can be seen in digital switching circuits. Saw tooth wave — these waves are non —sine waves. This wave pattern resembles to the teeth on blade of saw. Triangle wave- this wave pattern is triangle in shape and contains only odd harmonics. Introduction to sound waves: The term sound refers to the physical sensation that stimulates our ears.
In constructing sound, there must be a source for a sound. The source of a sound wave is vibrating object. A disturbance that travels or propagates through space and time, usually by transference of energy is known as a Wave. A wave is a disturbance by which energy is transferred. A wave which causes disturbance in the direction of its propagation is known as a longitudinal wave, whereas a wave which causes disturbance perpendicular to the direction of its propagation is known as a transverse wave.
Sound waves are the one of the most important examples of longitudinal waves. Loudness and pitch are two aspects of any sound and each refers to a sensation in the consciousness of the listener. The lower the frequency, the lower is the pitch and the higher the frequency, the higher is the pitch.
For an example, a bird makes a high pitch besides a lion makes a low pitch. Sensitivity of the human ear is around 20 Hz to 20 Hz. They can generate by musical instruments, human vocal cords and loudspeakers. It is also the distance the wave travels before the pattern repeats itself and is measured in metres m. It is measured in seconds s. Frequency is the number of oscillations per unit time at any point and is measured in hertz Hz.
Displacement x is the distance any part of the wave has moved from its mean position. It is always positive and is measured in metres m.
