Solve the following questions given below:
Question 1) why do atoms have discrete spectral lines?
Question 2) Is it possible for different atomic transitions, in a particular atom, to give off the same color photons? Why?
Question 3) A beam of red photons and blue photons are sent through a diffraction grating simultaneously. Sketch the diffraction pattern of both colors.
Question 4) The spectrometer provided is able to measure angles to a precision of 1 minute (1'). Given that 60'=1degree, convert the following angles, 31degree 21' and 12degree 5', into degrees.
I need the right answer and steps of solving these questions. Thanks!
