So there's not really any practical way of working this out unless I actually carry through with the experiment? This is high school standard so I assume I don't need to go into such great detail. Could anyone provide me with a hint as to when the absorbance plateaus off which I can base my...
Hi, I'm doing an investigation into the absorbance of UV light by glass of varying thickness (constant density and standard type of glass) for an assigment. However, we're not actually supposed to carry out the investigation due to time constraints, so we're meant to make up the numbers...
So is my description of a potential setup okay? I gave it some further thought and I believe that if I can obtain a value for current, I should able to observe the number of photons and hence the intensity because I=q/t. Hence if I divide the total charge per second by the charge of an electron...
Hi, I'm trying to find out how changing the current fed through to a filament (e.g. sodium) of a lamp would change the light intensity. To determine the relationship, I will first need to find out how to measure the intensity of light. I've thought of one possible way to do it, but the...
