The frequency of a wave is the number of waves that pass by each second , and is measured in Hertz (Hz). For example, a sound wave might have a frequency of 450 Hz.
Read moreWhat is the role of frequency in sound?
The higher the frequency waves oscillate, the higher the pitch of the sound we hear . As you see, sound frequency is determined by the way in which sound waves oscillate whilst travelling to our ears, meaning that they alternate between compressing and stretching the medium, which in most cases is air.12 Şub 2020

Read moreWhat is an example of a high frequency?
High-frequency words are those which appear most often in our language – many are also common exception words (e.g. ‘I’, ‘the’, ‘you’ ). Children need to recognize these words by sight, without having to use sounding out strategies, because they occur so frequently in writing.
Read moreWhat does high frequency mean in science?
High frequency is the ITU-designated range of radio frequency electromagnetic waves between 3 and 30 MHz . Also known as the decameter band or decameter wave as the wavelengths range from one to ten decameters.
Read moreWhat does high frequency mean?
High frequency (HF) is an electromagnetic frequency defined by the International Telecommunications Union (ITU) for radar and radio communications . It operates in a range of three to thirty MHz and as the wavelengths spread over ten to one hundred meters, it is also known as decameter wave and designated as band 7.
