If we can produce plastic beads incorporating m distinct molecules (i.e. m different emission wavelengths) with n different concentrations of each dye, how many distinct beads could be made? Calculate this number for (m=2, n=10) and (m=4, n=20).

please can you explain how to do it step by step;

calculate the following wavelength in m for the following hydrogen atom electronic transitions:

1. n=4 to n=2 = 9.72 *10^-8 m

2. n=4 to n=2 = 4.86*10^-7 m

3. n=4 to n=3 = 1.875 * 10^-6 m

4. based on the questions above. in which region of the electromangnetic radiation spectrum would each of these transitions occur?

5. state two additional electronic transitions for hydrogen atoms that produce emissions in the visible region.

**Just need help with questions 4 and 5 **
