Particle Model of waves Total mark: 10 Follow the example below to solve question 1. Energy of a Photon E = hc 1240 eV-nm A A Use E = 1240 eV.nm/> to solve the following problems. 1. What is a photon's energy if the photon's wavelength is 515 nm? _1240 ev.nm_1240 515 = 2.41 eV 1.1 Calculate the Energy of photons that have a wavelength A= 320 nm and 811 nm 1.2 Rank the following photons from least to greatest energy. a. 4.0 eV b. 320 nm c. 811 nm d. 2.1 eV Follow the rule below to solve exercise 2. Wavelength = Speed of Light Frequency of Oscillation Frequency of Oscillation = Speed of Light Wavelength 2.1 Find the frequencies of a photon of wavelength 320x10-9m. 2.2 Find the wavelength of a photon of frequency 7x1014 Hz.In photoelectric effect: - Electrons eject from the cathode only if the frequency of the incident radiation is greater than a certain minimum value, called the threshold frequency {fa}. Does the graph below conrm this statement? Justify. Constant Intensity Current 3'0 Frequency
