Science of Sound
Definition of terms:
Sound - a form of energy created by vibrationg objects.
Solids are best transmetters of sounds.
Frequency - is the number of vibration per seconds which the ear receives.
Intensity - is the rate at which the sound energy moves through a unit area to determine the pitch of sound.
Pitch - refers to the highness or lowness of tone.
Sound is produced by vibration with fundamental propeties such as frequency & intensity in a medium such as solid, liquid & gas.
Light is a form of energy. It travels in a straight line. It has speed of approximately 3.0 x 108 m/s. It separates into differet colors known as spectrum. Rainbow is the spectrum of sunlight. It is disperse in different color such as red, orange, yellow, green, blue, indigo and violet.
Light rays are regularly reflected by smooth shiny surfaces and are irregularly reflected by rough surfaces. It is refracted when they pass at an angle from one medium to another.
