The pressure is low in the HC lamp as a result more natural uncertainty broadening. c. In the HC lamp, the temperature is low so that the Doppler Effect is high causing more broadening. d. In flame, the gas temperature is high so that the collision is higher and resulting more broadening.arrow_forward13-15 Match the scientist with the accomplishment.Choices: [A] de Broglie [B] Einstein [C] Heisenberg [D] Planck [E] Rydberg13. Explained the photoelectric effect by assuming light behaves as if composed of particles which he called photons.14. Suggested that light and matter both had wavelike characteristics. His equation allows the calculation of the wavelength of an electron and other objects.15. Showed that it was impossible to know where an electron is and its momentum exactly at the same time.arrow_forwardLearning Goal: To understand the experiment that led to the discovery of the photoelectric effect. In 1887, Heinrich Hertz investigated the phenomenon of light striking a metal surface, causing the ejection of electrons from the metal. The classical theory of electromagnetism predicted that the PORA that the energy of the electrons ejected should have be have been proportional to the intensity of the light. However, Hertz observed that the energy of the dont of the interio electrons was independent the intensity of the from light. Furthermore, for low enough frequencies, no electrons were ejected, no matter how great the intensity of the light became. The following problem outlines the methods used to investigate this new finding in physics: the photoelectric effect. Part B Suppose that the light carries energy Elight. What is the maximum stopping potential Vo that can be applied while still allowing electrons to reach the detector? Express your answer in terms e, Elight, and p. ► View…arrow_forward

No, because blue light photon has lower energy due to smaller wavelength compared with the red-light photon. B.
