Study Notes
Waves
Waves are a form of energy transfer through matter or space. They have three fundamental characteristics: amplitude, wavelength, frequency, absorption, and transmittance. Each of these properties plays a crucial role in understanding how waves behave and interact with their environment.
Amplitude
Amplitude is the maximum displacement of a wave from its equilibrium position. It determines the height of the peak or depth of the trough of a sinusoidal wave. Higher amplitude waves have more energy compared to lower amplitudes. For example, in electromagnetic radiation, higher amplitude means higher intensity or power.
Wavelength
The wavelength of a wave is the distance between two consecutive points on the wave that are in phase. In other words, it's the distance between two wave crests or two wave troughs. A longer wavelength corresponds to lower frequencies, while a shorter wavelength indicates higher frequencies.
Frequency
Frequency is the number of oscillations per unit time taken by a particle to move from one extreme of vibration to the other and back again. It's measured in hertz (Hz) or cycles per second (cps). Higher frequency waves correspond to shorter wavelengths and vice versa.
Absorption
Absorption refers to the process where energy from a wave is transferred to another system. This can occur when a wave encounters a medium like air, water, or solid matter. When waves interact with matter, they can be partially absorbed, reflected, or refracted depending on the properties of both the wave and the material it is passing through.
Transmittance
Transmittance refers to the ratio of transmitted light to incident light. It describes the fraction of light that passes through a material without being absorbed, scattered, or reflected. High transmittance materials allow most of the incident light to pass through them, making them useful for applications such as lenses, mirrors, and solar panels.
