Two identical waves (having the same wavelength and amplitude) interfere with each other. The initial amplitude of each wave was 28 cm; the resultant wave has an amplitude of 12 cm. What is the phase difference between the waves represented as a fraction of a wavelength?
Sum Of Squares
A statistical measure used to describe the dispersion or variability within a data set, calculated as the sum of the squared differences from the mean.
Error
The difference between the observed value and the true value due to measurement or estimation inaccuracies.
Multiple Regression Analysis
A method in statistics that employs multiple predictor variables to estimate the result of a dependent variable.
SSE
Sum of Squared Errors, a measure of the discrepancy between the data and an estimation model, indicating the total deviation of data points from the fitted values.
