Determine whether the following transitions are emission or absorbance. n = 5 → n = 3 n = 9 → n = 8  n = 1 → n = 4  Which of the transitions involves a photon of the longest wavelength?

Human color vision is " produced" by the nervous system based on how three different cone receptors interact with photons of light in the eye. These three different types of cones interact with photons of different frequency light, as indicated in the following chart: Cone Type Range of Light Frequency Detected S 6.00-7.49 1014s1 M 4.76-6.62 1014s1 L 4.28-6.00 1014s1 What wavelength ranges (and corresponding colors) do the three types of cones detect?

Which photons contain more energy, X-ray photons with a frequency of 31017 Hz or ultraviolet photons with a frequency of 21015 Hz? X-ray photons Ultraviolet photons Neither. They both contain the same energy per photon.

Calculate the energy per mole of photons (in kJ/mol) for red light with a wavelength of 700 nm. Calculate the energy per mole of photons (in kJ/mol) for UV-B light with a wavelength of 300 nm. How many times more energetic is this UV-B than this red light?
