front 1 VIBRATIONS | back 1 Vibration is a repetitive back-and-forth movement of an object or a medium, typically around a fixed position or equilibrium point. |
front 2 PITCH | back 2 Pitch is the degree of highness or lowness of a sound. It's what makes one sound different from another, like the difference between a high-pitched whistle and a low-pitched drumbeat. |
front 3 AMPLITUDE | back 3 In simple terms, amplitude refers to the maximum extent of a vibration or oscillation, measured from the position of equilibrium. In other words, it's the distance from the middle point (or resting position) of a wave to its highest or lowest point. Amplitude is a measure of the "size" of a wave or oscillation, indicating how much energy it carries or how intense its effect is. |
front 4 FREQUENCY | back 4 Frequency refers to the number of occurrences of a repeating event within a specific period of time. In simpler terms, it's how often something happens. For example, if you hear a clock ticking once every second, the frequency of the ticking sound is 1 hertz (Hz), which means it happens once per second. |
front 5 OSCILLATION | back 5 Oscillation refers to the back-and-forth movement or vibration of something. When it comes to sound, oscillation refers to the rapid back-and-forth movement of air molecules. In simple terms, when an object (like a speaker or vocal cords) vibrates, it pushes nearby air molecules back and forth. This movement creates waves of compressed and rarefied air, which we perceive as sound. So, oscillation in sound is essentially the movement of air molecules that creates the sensation of hearing. |
front 6 INTENSITY | back 6 Intensity refers to the strength or level of something. In sound, intensity is a measure of the amount of energy carried by sound waves per unit area. It determines how loud or soft a sound is perceived. Higher intensity sound waves carry more energy and are perceived as louder, while lower intensity sound waves carry less energy and are perceived as quieter. |
front 7 WAVELENGHT | back 7 In simple terms, wavelength refers to the distance between two consecutive peaks (high points) or troughs (low points) in a wave. For sound waves specifically, wavelength represents the physical distance between two consecutive compressions (where the air molecules are squeezed together) or rarefactions (where the air molecules are spread apart) as the sound wave travels through a medium, such as air or water. So, in essence, the wavelength of a sound wave tells us how long the wave is from one peak or trough to the next, |
front 8 SOUND WAVES | back 8 Sound waves are mechanical waves that spread through a medium, typically air, but they can also travel through other materials like water or solids. These waves are created by the vibration of particles within the medium. When an object vibrates, it causes nearby particles in the medium to also vibrate, transmitting the energy of the vibration through the medium in the form of a wave. |
