• ### Intel i5 vs i7: how important is the frequency?

I want to buy a notebook for around 800-1000 Euro and noticed the following: Cheaper Laptops with intel i5 processors have about 3.2 GHz on average, whereas more expensive intel i7 laptops only have about 2.4 GHz on average. Does that mean that the i5 laptop is faster? Also, some have 2 cores and some 4; how important is that?

• ### Solve equation tan((pi/4)-arctan(pi/(1+pi))?

I seem to be doing something basic wrong: Is it not = tan(pi/4)-tan(arctan(pi/(1+pi))) = tan(pi/4)-(pi/(1+pi))? Thank you

• ### When I convert from radiance to radiant intensity, can I simply multiply with the surface area of the emitter?

Radiance: W*sr^-1*m^-2 Radiant Intensity: W*sr^-1 It would work from the units and make sense, but do I need to multiply it with some constant as well?

• ### Can you spot my error with Planck's law?

Hi! I am trying to plot a blackbody curve at 5010K using Planck's law: This is my formula: f(x) = 2*1.19*(10^-16)/(x^5)*(exp(0.01439/5010x)-1) Written out with all constants: f(x) = (2*6.626*(10^-34)*(299792458^2))/((x^5)*((exp(2.626*(10^-34)*299792458)/(x*1.381*(10^-23)*5010.8))-1)) With both, I am not getting a blackbody curve, but some... show more

• ### What is a good value for the surface area of the tungsten wire in a Halogen bulb and a normal tungsten bulb?

I am trying to calculate the power of these bulbs using Stefan-Boltzmann's law and I have the temperature already. Does anyone know what the approximate surface area of the wire which is being heated is in a halogen and a normal tungsten bulb? halogen should be smaller.

For a school essay, I have measured the spectrum of different light bulbs and I want to adapt it to the efficiency of the human eye. Basically, I need to multiply the intensity of each wavelength with the corresponding efficiency. However, I have the efficiencies for each value of 5 nm (400, 405, 410 etc.), but my data is never on exact numbers but always around those. (399.2, 401.3, etc.). Is there any way, in which I can make excel find me the values in between these two points, treating it like a linear function? That would be very helpful, otherwise I will have to do like 600 of those manually.
