Answer:
In physics, the wavelength of a wave is the distance between two adjacent points on the wave with the same phase. The wavelength of a wave determines its frequency, which is the number of cycles of the wave that pass a given point in a given time period.
The relationship between wavelength, frequency, and the speed of the wave is described by the equation:
wavelength (λ) = speed (v) / frequency (f)
This equation shows that as the wavelength of a wave increases, its frequency decreases, and vice versa. The speed of a wave is determined by the medium through which it is traveling, and is constant for a given type of wave in a given medium.
For example, the wavelength of radio waves can range from millimeters to kilometers, while the frequency of radio waves ranges from kilohertz to gigahertz. The speed of radio waves is the speed of light in a vacuum (299,792,458 meters per second), so the wavelength of a radio wave with a frequency of 1 MHz (1 million cycles per second) would be approximately 300 meters.
Wave energy is the energy that is carried by a wave as it travels through a medium. It is related to the amplitude, or height, of the wave, as well as its frequency and wavelength. The amount of wave energy in a given area is determined by the square of the wave's amplitude and the inverse of its wavelength.
