The properties of a wave, including its frequency, speed, amplitude, and wavelength, can be determined by both the properties of the wave's medium and the way the wave is generated (i.e., the wave's source). Let's look at each of these factors individually:
Frequency: The frequency of a wave is determined by the source of the wave. It represents the number of complete oscillations or cycles the wave undergoes per unit of time. Frequency is measured in hertz (Hz) and is influenced by the properties of the wave's source, such as the vibrating object or the frequency at which an electromagnetic source oscillates.
Speed: The speed of a wave is primarily influenced by the properties of the medium through which the wave travels. For example, in the case of sound waves, the speed depends on the properties of the medium, such as the density and elasticity of the material. In general, the speed of a wave is given by the equation: speed = frequency × wavelength.
Amplitude: The amplitude of a wave is determined by the energy or force that generates the wave. It represents the maximum displacement or distance that a particle in the medium moves from its equilibrium position as the wave passes through it. The amplitude can be influenced by the properties of the wave's source and the medium through which the wave propagates.
Wavelength: The wavelength of a wave is primarily determined by the properties of the medium. It represents the distance between two consecutive points in the wave that are in phase with each other. In some cases, the source of the wave can also affect the wavelength, especially in situations where the source is capable of generating waves with specific wavelengths or frequencies.
In summary, the properties of the wave's medium play a significant role in determining the speed and wavelength of the wave. On the other hand, the source of the wave contributes to the frequency and can have some influence on the amplitude.
