is there going to be any problems such as finding wave length as well as quantity of energy emitted for example E=hc/wavelength the h and the c are constants so do we have to memorize those numbers or it will be given to us and we just need to calculate it ? As well as the calculation part is there any parts that u have to multiple numbers like this (-2.18X10^-18)(-5/36) because it takes a while to answer these and its timed ?
