The Wave Nature of Light (Section)
(a) What is the frequency of radiation that has a wavelength of 10 μm, about the size of a bacterium?
(b) What is the wavelength of radiation that has a frequency of 5.50 × 1014 s-1?
(c) Would the radiations in part (a) or part (b) be visible to the human eye?
(d) What distance does electromagnetic radiation travel in 50.0 ms?
Chemistry 121 Notes for Chapters 0-2: Chapter 0: Accuracy: How close a measured value is to the known actual value. Precision: How close measurements are to each other. Significant Figures: The total number of digits recorded for a measurement -The last digit is estimated Counting sigfigs: With no zeros: there are as many sigfigs as there are digits With zeros inbetween 2 non-zero digits: always counted Zeros at the beginning: Never counted Zeros at the end AND before a decimal: always counted Addition and subtraction with sigfigs: Round to the smallest number of digits after the decimal point Multiplication and division with sigfigs: Round to the smallest number of TOTAL sigfigs Chapter 1: Atomic symbol: the single/double letter for the elements Peri
