5. Planck's equation relates the energy of a photon of light to its frequency. E= hv Where Planck's constant h =6.64 x 10-34 J-s And frequency (v) is measured in 1/seconds or hertz (Hz) If the frequency of a red spectral line is 1.60 x 1014 Hz, how much energy does one photon of this light have? a. b. If the frequency of a violet spectra line is at 2.50 x 1014 Hz, how much energy does one photon of this light have?

Question
5. Planck's equation relates the energy of a photon of light to its frequency. E= hv Where Planck's constant h =6.64 x 10-34 J.s And frequency (v) is measured in 1/seconds or hertz (Hz) If the frequency of a red spectral line is 1.60 x 1014 Hz, how much energy does one photon of this light have? a. b. If the frequency of a violet spectra line is at 2.50 x 1014 Hz, how much energy does one photon of this light have? 6. The visible light spectrum represents only a small portion of the electromagnetic spectrum. Infrared and ultraviolet radiations lie directly outside the visible range. * UV radiation is dangerous and is located just past the violet region on the spectrum. *IR radiation is harmless and is located just before the red region on the spectrum. Based on your calculations in question 5 above, explain why you think UV is more dangerous than IR.
