Terahertz radiation – also known as submillimeter radiation, terahertz waves, tremendously high frequency [1] (THF), T-rays, T-waves, T-light, T-lux or THz – consists of electromagnetic waves within the International Telecommunication Union-designated band of frequencies from 0.1 to 10 terahertz (THz), [2] (from 0.3 to 3 terahertz (THz) in ...

The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), often described as being equivalent to one event (or cycle) per second. [1] [a] The hertz is an SI derived unit whose formal expression in terms of SI base units is s −1, meaning that one hertz is one per second or the reciprocal of one second. [2]

The following list illustrates various frequencies, measured in hertz, according to decade in the order of their magnitudes, with the negative decades illustrated by events and positive decades by acoustic or electromagnetic uses. Acoustic – frequency of G −7, the lowest note sung by the singer with the deepest voice in the world, Tim Storms.

但是，我们经常会遇到不同的频率单位，有时候是 THz ，有时候是 cm-1 。 而 phonopy 给出的单位是THz，如何在phonopy中切换单位？ 单位之间的转换比例是多少？

太赫兹 (THz) 单位定义. The terahertz is a multiple of the unit hertz (Hz) for frequency. The International System of Units (SI) defines the prefix tera (T) as a factor of 10¹² or 1000000000000. Per this definition, one terahertz is 10¹² hertz. The terahertz is represented by the symbol THz. SI …

Convert terahertz (THz) to another unit of frequency such as hertz, kilohertz, or megahertz, and see the conversion formulas.

太赫兹(THz)与其它频率单位在线换算，包括赫兹,兆赫,千兆赫,千赫,周/秒,周/毫秒,周/微秒.....

One THz is a very high frequency unit of electromagnetic (EM) wave frequency equal to one trillion hertz (10-to-the-12th power Hz) Our table (below) provides definitions of various frequencies or oscillation rates expressed in kilohertz, megahertz, gigahertz, or terahertz.

太赫兹波是一种电磁波，频率在 0.1THz 到 10THz 之间，波长在 3mm~0.03mm 之间。 对于任何一种电磁波，都可以用波长和频率对其进行区分和描述，他们满足如下关系： λ=C*T，λ =C/f. 其中，λ是波长， T 是周期， f 是频率，为 T 的倒数， C 是光速，根据光束恒定的价格， C=3 × 10^8m/s。 根据这个公式，就可以进行波长和频率的换算。 例如频率 1THz，即 1 × 10^12 Hz，对应的波长就是λ =C/f=3 × 10^8/1 × 10^12 Hz=3 × 10^ (-4)m，单位变成毫米就是 0.3mm。 经 …
