1) The number of cycles an oscillator completes in one second is known as its frequency. Frequency is measured in units called Hertz (Hz). To find the frequency of an oscillator, you can count the number of cycles it completes in one second.
2) The force that always acts to pull a system back toward its equilibrium position is called the restoring force. It is a force that counteracts any displacement from the equilibrium and tries to restore the system to its original position. Examples of restoring forces include the force exerted by a spring when it is stretched or compressed, or the force of gravity pulling an object towards the ground when it is displaced vertically.
3) The distance from one point on a wave to the same point in the next cycle of the wave is called the wavelength. Wavelength is typically represented by the symbol λ (lambda) and is measured in units of length, such as meters or centimeters. To determine the wavelength of a wave, you can measure the distance between corresponding points, such as crest to crest or trough to trough.
4) The bending of a wave as it crosses the boundary between two materials is called refraction. Refraction occurs when a wave changes direction and possibly speed as it moves from one medium to another with different properties, such as density or refractive index. The change in speed and direction causes the wave to bend or deviate from its original path.
5) The type of wave interaction that occurs when a wave bounces off a surface is called reflection. Reflection happens when a wave encounters a boundary or obstacle and part or all of the wave is redirected back into the original medium. Examples of reflection include sound waves bouncing off walls, light waves reflecting off a mirror, or water waves reflecting off a shoreline.
6) The phenomenon that causes the apparent change in a pencil's shape when it enters water is called refraction. Refraction occurs because light waves travel at different speeds in different media, causing them to change direction when they pass from one medium to another. This change in direction makes the pencil appear bent at the point where it enters the water.
7) The loudness of sound is measured in units called decibels (dB). Decibels are a logarithmic scale used to quantify the intensity or magnitude of sound. The greater the number of decibels, the louder the sound. Sound level meters are commonly used to measure the decibel level of sound in various environments or situations.
