1. Frequency

   Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency for clarity, and is distinct from angular frequency. Frequency is measured in hertz (Hz) which is equal to one event per second. The period is the interval of time between events, so the period is the reciprocal of the frequency.For example, if a heart beats at a frequency of 120 times a minute (2 hertz), the period, T—the interval at which the beats repeat—is half a second (60 seconds divided by 120 beats). Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light.

1. Frequency

   Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency. For example, if a newborn baby's heart beats at a frequency of 120 times a minute, its period is half a second.

   Saptarshi Bandyopadhyay wrote in the proposal. Notional view of LCRT on the far-side of the Moon. ( Courtesy of Saptarshi Bandyopadhyay)( Saptarshi Bandyopadhyay) LCRT could enable tremendous scientific discoveries in the field of cosmology by observing the early universe in the 1050m wavelength band( i.e., 630MHz frequency band), which has not been explored by humans to date.
