The light which is produced in the core of the sun passes through layers of comparatively cold gas clouds on the surface of the sun. These clouds absorb some of the sun's light producing dark lines in the spectrum of the sun and sky. Two of the lines, called Fraunhofer C and I) lines after their discoverer, are found at about 656 nm and 587 nm, respectively. Looking at your atomic spectroscopy data, which elements that you examined would absorb at these wavelengths

Ahypothesis is? close agreement by competent observers of observations of the same phenomena. a guess that has been tested over and over again and always found to be true. an educated guess that has yet to be proven by experiment. the long side of a right triangle. a synthesis of a large collection of information that includes guesses.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
