51 The image below is data from a star. What is seen in this image? A line graph of light absorption at various wavelengths. The x axis is labeled wavelength in nanometers and the y axis is labeled brightness. The line inclines to 350 nanometers then begins to experience segments of rapid incline and decline until peaking at around 430 nanometers and declining steadily after. a. an absorption spectrum only b. a continuous spectrum only c. a continuous spectrum with absorption lines d. a continuous spectrum with emission lines e. an emission spectrum only 1 points Question 52 The amplitude of a wave is a. a measure of the wave's velocity. b. the total distance that a wave travels. c. the distance between one peak value and the next peak. d. the number of peaks that pass per second. e. the maximum height of the wave above zero
