Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF).

As a result, many Christmas Carols can be related to St Stephen's Day (26 December), St John's Day (27 December), Feast of Holy Innocents (28 December), St Sylvester's Day (31 December), and the Epiphany. Examples of this are "We Three Kings" (an Epiphany song), and "Good King Wenceslas" (a carol for St. Stephen's Day ).

A carol is a festive song, generally religious but not necessarily connected with Christian church worship, and sometimes accompanied by a dance. A caroller (or caroler) is someone who sings carols, and is said to be carolling (or caroling).
Very high frequency ( VHF) is an ITU designation of radio frequencies. [1] . The designation has all frequencies between 30 megahertz to 300 megahertz. Behind the VHF frequencies is called high frequency (HF). Above the VHF frequencies is called ultra high frequency (UHF).
Dec 22, 2022 · From the lullaby-like Away in a Manger to the rabble-rousing Good King Wenceslas, Christmas carols have been sung around the world for hundreds of years, and have existed since as early as 4th century AD. However, in spite of their universal nature today, the origins of many carols remain obscure.
Principle 1: Higher pitch corresponds to higher frequency. Recall that the frequency f f of a sound wave describes how many vibrations there are per second. This is the most important quantity here, because the frequency remains constant as the sound wave travels from its source through the medium into our ears.
