The subject of chemistry is incredibly significant since it is from all around you! It’s in your food, your clothes, your water, your medicines, your air, your cleaning agents… you name it. Chemistry is commonly referred to as the “key science” since it links other sciences including biology, quantum mechanics, geology, as well as geoscience. Notwithstanding these benefits, many learners gripe about chemistry because it qualifies for much the same course credits like any other class but asks a lot more of you even outside class. However, my homeworkwriters can help you with your tasks. Here’s a sample of such a question:
A monochromatic laser is exciting hydrogen atoms from the n=2n=2 state to the n=5n=5 state.
Part A
What is the wavelength λ of the laser?
Express your answer to three significant digits in nanometers.
Part B
Eventually, all of the excited hydrogen atoms will emit photons until they fall back to the ground state. How many different wavelengths can be observed in this process?
