| 1. | Define the following terms. Also, write their SI units(a) amplitude(b) time period(c) frequency | 
| Answer» b)time period(denoted by 'T' ) is thetimeneeded for one complete cycle of vibration to pass in a given point. As the frequency of a wave increases, thetime periodof the wave decreasesSI unit is second c)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.SI unit - HZ a) Amplitude is the maximum displacement of points on a wave, which you can think of as the degree or intensity of change. This maximum displacement is measured from the equilibriumSI unit is meter | |
