By joining chemistry steps, you will gain instant access to the answers and solutions for all the practice problems, quizzes, and the powerful set of general chemistry 1 and 2 summary study guides. 5. calculate the number of photons in a laser pulse with a wavelength of 624 nm that contains 4.19 mj of energy. Figure 5.2.2 5.2. 2: (a) a wave consists of alternating crests and troughs. the wavelength (λ) ( λ) is defined as the distance between any two consecutive identical points on the waveform. the amplitude is the height of the wave. (b) a wave with a short wavelength (top) has a high frequency because more waves pass a given point in a certain. Practice problems 1. 6a photon has a frequency ( ) of 2.68 x 10 hz. calculate its energy. ans: e = 1.78 x 10 27 j 2. calculate the energy (e) and wavelength ( ) of a photon of light with a frequency ( ) of 6.165 x 1014 hz. ans: e = 4.1 x 10 19 j = 4.87 x 10 7 m 3. calculate the frequency and the energy of blue light that has a wavelength of. Shown below are the wavelengths of x rays emitted by some elements: element wavelength (Å) cr 2.291. fe 1.937. co 1.790. cu 1.542. mo 0.7107. calculate the frequency of each x ray emitted and use that data to predict the wavelength of the light emitted by zirconium. hint: plot the square root of ν versus the atomic number of the element.
