How wavelength and frequency are related?

As a domain expert in physics, I can explain the relationship between wavelength and frequency. Wavelength and frequency are inversely proportional to each other. This means that as the frequency of a wave increases, its wavelength decreases, and vice versa. This relationship is governed by the speed of light, which is a constant in a vacuum. The speed of light (c) in a vacuum is approximately 299,792,458 meters per second (m/s). The relationship between the speed of light, frequency (f), and wavelength (λ) is given by the equation: \[ c = f \times \lambda \] Where: - \( c \) is the speed of light in a vacuum, - \( f \) is the frequency of the wave, and - \( \lambda \) is the wavelength of the wave. Using this equation, we can see that if the frequency increases, the wavelength must decrease to maintain the constant speed of light, and if the frequency decreases, the wavelength can increase. Now, let's translate this into Chinese: 作为一名物理学领域的专家，我可以解释波长和频率之间的关系。波长和频率是彼此成反比的。这意味着，当一个波的频率增加时，它的波长就会减少，反之亦然。这种关系由光速决定，光速在真空中是一个恒定的值。 光在真空中的速度（c）大约是每秒299,792,458米（m/s）。光速、频率（f）和波长（λ）之间的关系由以下方程给出： \[ c = f \times \lambda \] 其中： - \( c \) 是光在真空中的速度， - \( f \) 是波的频率， - \( \lambda \) 是波的波长。 通过这个方程，我们可以看到，如果频率增加，为了保持光速不变，波长必须减少；如果频率减少，波长可以增加。

The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.
