Thank you for your reply! So I am aware that the energy is conserved, I am just not sure where does the formula for intensity breaks down. If you measure, say, the intensity of the main peak, you get a finite value. Now, the formula for where the other peaks will be imply that for an infinitely...
Hello! I am a bit confused by the formula for light intensity in the case of interference. In the books and online resources that I read, this is given as: $$I = I_0 \cos^2(\frac{\pi d \sin \theta}{\lambda})$$ where ##d## is the distance between the slits, ##\lambda## is the wavelength of the...
