<human>:  Logarithms equations used everyday
<bot>: Logarithmic equations are used everyday in scientific and engineering calculations, such as calculating the size of an antenna based on its gain or computing the acceleration due to gravity from a given height. 2 Logarithmic equations are also used everyday to calculate the amount of time a sound wave needs to travel a given distance or the amount of power a light bulb needs to produce a certain amount of illumination. 3 Additionally, logarithmic equations are used in meteorology to estimate the atmospheric pressure or wind speed based on height, and in financial applications such as compound interest calculations or stock market analysis.
