Anonymous users2024-02-11Wavelength Frequency = speed of light (speed of waves), because light is an electromagnetic wave, so the speed of electromagnetic waves is the speed of light.
The "Wave Velocity" is determined by the "medium".
Frequency" is determined by the "wave source".
The "wavelength" is determined by the "medium" (wave velocity v) and the "wave source" (frequency f). （λ=v/f）
Thus, according to quantum theory, there is =c, where is the wavelength of the electromagnetic wave, is the frequency of the electromagnetic wave, and c is the speed of light.
Where, according to the theory of relativity, c is a constant and c = 300,000 kilometers per second, so the wavelength and frequency are inversely proportional.
Extended Materials. Wavelength refers to the distance traveled by a wave in a vibrational cycle. That is, the distance between two adjacent vibrational potentials that are 2 apart from each other along the direction of wave propagation.
Wavelength is equal to the product of the wave velocity u and period t, i.e. =ut. Waves of the same frequency propagate at different speeds in different mediums, so the wavelengths are also different.
Frequency, which is the number of times a periodic change is completed per unit of time, is a quantity that describes the frequency of periodic motion, and is commonly represented by the symbol f or , the unit is one second and a minute, and the symbol is s-1. In order to commemorate the contribution of the German physicist Hertz, people named the unit of frequency hertz, abbreviated as "hertz", and the symbol is hz. Every object has an amplitude-independent frequency that is determined by its own properties, called natural frequencies.
The concept of frequency is used not only in mechanics and acoustics, but also in electromagnetics, optics and radio technology.

where v is the speed of the wave, f is the frequency, and is the wavelength.

Anonymous users2024-02-09The relationship between wavelength and frequency is that wavelength and frequency are inversely proportional.
According to the formula for the speed of the wave v= f In the same medium, the propagation speed of the wave is the same, and the product of the wavelength and frequency is constant, =v f, the wavelength and frequency are inversely proportional, i.e., the higher the frequency, the shorter the wavelength.

Frequency <>
It is the number of waves that pass through a specified place in a fixed time, i.e., <> and thus <> by the previous wavelength
, we can get the relationship between wavelength and frequency as: propagation velocity <> in <>
The unit is m s (meter second) and the frequency is <>
The unit is hertz (Hz, abbreviated as hertz) and the wavelength is <>

Anonymous users2024-02-07Wavelength and frequency are two important physical quantities, and the relationship between them can be expressed by the following formula: wave velocity = wavelength frequency, where the annihilation wave velocity is the speed at which the wave propagates in the medium, and the single leg source is meters per second (m s); Wavelength is the length of the wave, and the unit is meters (m); The pure tremor frequency is the number of vibrations of the wave in hertz (Hz). According to this formula, we can get the relationship between wavelength and frequency:
Wavelength = Wave Speed Frequency, that is, the wavelength is inversely proportional to the frequency, the higher the frequency, the shorter the wavelength; The lower the frequency, the longer the wavelength. This relationship has a wide range of applications in the fields of optics and acoustics.

Anonymous users2024-02-05Frequency vs. wavelength of light:
u f, where u is the speed of the wave and f is the frequency.
The process is as follows:
1) The wavelength is equal to the product of the wave velocity u and the period t, i.e. =ut.
2) The frequency f=1 t obtains: t=1 f. (This is the relationship between perimeter and frequency) 3) t=1 f is substituted for =ut, and =u f is obtained.
The units of u f: m, m s, hz respectively.
Wavelength vs. frequency:Frequency is the number of waves passing through a specified place at a fixed time, i.e., v=1 t. And the expression for wavelength is =ut, and the relationship between wavelength and frequency can be obtained as:
u/v。The unit of propagation velocity in the sub-relation is meter seconds, the unit of frequency f is hertz, and the unit of wavelength is meters.
Example: If a broadcasting frequency used in a broadcasting program is 639kHz (kilohertz), and the propagation speed of electromagnetic waves in the air is the speed of light three times ten to the eighth power of the nuclear thickness per second, then the wavelength of the radio wave of the program can be calculated = 300000000m s 639000hz=.
Light has waves, so it has a certain wavelength, just like sound, and we can't see it, but we can hear it. The difference in the wavelength of light causes the difference in color, and the wavelength is just the property of the beam, not the essence. Can you understand that?

God or god is only one of the religious ideas, the highest of the supernatural beings, generally considered to have no physical body, but a physical image. It is not limited by the laws of nature, but on the contrary, it is higher than the laws of nature, dominates the material world, and can influence the material world. This concept exists in almost all human societies, but depending on the culture, people's ideas about God are ever-changing. >>>More
