So using the standard equation: E = hf, we can find the relationship between light intensity and wavelength as follows: c = lambda x f Therefore, f = c/lambda substitute this in the standard equation to get: E = (h c)/lambda Where h = planks constant, and c = speed of light.
When you increase light intensity, does the wavelength increase or decrease? For example, I have a lamp with 4V and 8V option, when it is at 4V, it is dimmer than at 8V. My question is whether or not it has anything to do with an increase or decrease in wavelength.
