WebThe midpoint of a class, which is also called a class mark, is halfway between the lower and upper limits. True. A class interval, or class width, can be determined by subtracting the lower limit of a class from the lower limit of the next higher class. True. To convert a frequency distribution to a relative frequency distribution, divide each ... WebApr 11, 2024 · The number of times a wave repeat is a frequency, denoted by f. We know that distance is equal to the speed over time, the same goes for the wave speed: v (wave speed) = λ/t. Also, we know that the frequency is 1/t, putting this value in the above equation: v = fλ. This is the required equation linking wave speed frequency and wavelength.
WebStep 1: It is necessary to do the following steps in order to convert frequencies into relative frequencies.
