define wavelength, frequency, electric cell and loudness
Answers
Explanation:
Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave.
Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency.
An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or using electrical energy to cause chemical reactions.
In acoustics, loudness is the subjective perception of sound pressure. Loudness, a subjective measure, is often confused with physical measures of sound strength such as sound pressure, sound pressure level (in decibels), sound intensity or sound power.
