Question

(c) Find the linear relationship between frequency and wavelength (or function of wavelength ), in meters. Record the equation for the linear regression line, including units, and record the correlation units, and record the correlation value. S m 1.5 15 correlation = -.q841 s- m d) Calculate the frequency of radiation having a wavelength of 2.50 x 107 m (near-ultra of 2.50 x 10 m (near-ultraviolet region). In to the value of mx in the is a large number, the linear regression line performing the calculation, note that the y-intercept, b, is negligible compared to the value of mx straighe-line euation y - mx + b. Although the intercept is a large number, the linear regress essentially passes through the origin of your graph! (e) Explain the significance of the slope of your linear regression line. If you do not recognize the value and units of the slope, consult the list of physical constants in your textbook pbaw

Explanation / Answer

e)
The linear regression equation y=mx+b denotes graph between frequency, Vs (1/wavelength)
Mathematically slope, m = y/ x = frequency / (1/wavelength) = frequency*wavelength
but we know that C = * , where C = velocity of light
/ (1/) = (1/sec) / (1/m) = m/sec
Therefore slope signifies velocity of light
