I need help with 2 and 4 Thanks Students should Describe the relationship between energy (E), frequency (v) and wavelength (X) of electromagnetic radiations. Calculate either energy (E), frequency (v) or wavelength (lambda), given any one of them. Rank electromagnetic radiations according to energy, frequency and/or wavelength. Calculate. Describe Bohr's Model and calculate energy difference between energy levels in hydrogen atom. Use appropriate quantum numbers in atomic orbitals. Sample quiz/exam questions Arrange the following colors of light in order of increasing energy. violet infrared green blue microwave What is the energy, frequency and wavelength of photons involved in a transition from n = 2 to n = 4 levels in a hydrogen atom? Will photons be absorbed or emitted? Without any calculations, select all transition that will result in emission of photons and then rank these transition according to the wavelength of photons emitted. n = 1 to n = 3 n = 6 to n = 2 n = 10 to n = 100 n = infinity to n = 1000 n = 10 to n = infinity n = 2 to n = 1 When Vernier readings (degree) were plotted on y-axis, and wavelengths of line-spectra (nm) for Hg-Iamp were plotted on x-axis, the best-fit-line equation obtained from Excel was y = 0.204x+ 131.5 Predict where (the Vernier reading) you may find the faint purple line in Hg-lamp, which was very challenging to find in this lab. Which obital (or obitals) has the lowest energy for H atom? How about O atom? 2s 3p 3d 2p
