Please can someone show me the steps needed to go about rearranging the equation Eph = hc/lambda to make lambda (the wavelength of the light) the subject? I'm totally stuck and I have an exam in the morning. I suspect this is one of the questions that will come up. I know it should be simple but...

Hi, I'm looking for information on blood and neuron cells. Specifically I need to know how the membrane transport mechanism in blood and neuron cells work? I am aware of concepts such as active diffusion, facilitated diffusion, and simple diffusion. The task is to look at the membrane...
