UV Visible Spectroscopy

Spectroscopy refers to the absorption or emission of light or other radiations by matter. When a substance or chemical absorbs light or radiation, they reach an excited state followed by de-excitation or emission of the light or radiation forming distinct spectra. UV-visible spectroscopy or ultraviolet-visible refers to the absorption and emission in the ultraviolet and visible regions of the electromagnetic spectrum.

You are absolutely the BEST. Finally someone that dosen't calculate this exercise as 836f66dgsffjgvkik!!!! I understand everything you did, but I have one question. Some experts says that km can be calculated by saying Vmax from date divided by 2 and then they find Km by going down on x-axis on the graph. But, you used the MM equation, to solve for Km. Is both method the same? Or is one of them more precise than the other? *And if theres no need to reply back after you answering my question, then I will thank you again for your help. I have more these types of exam questions that I will probably upload later, and I hope someone like you will look at it.
