I Fluorescent lamps And Fan remote

AI Thread Summary
Fluorescent lamps can interfere with the operation of infrared (IR) remote controls due to the electromagnetic noise they generate. When the fluorescent lamps are on, this noise increases the noise floor, making the IR receiver less sensitive and reducing the effective range of the remote. In contrast, when the lamps are off, the remote works at a longer distance because there is less interference. This phenomenon highlights the impact of fluorescent lighting on electronic devices that rely on IR signals. Understanding this interaction can help users optimize their remote control experience.

Hi everyone. I hope you are doing great . I recently saw something interesting and had a question. I use fluorescent lamps in my room, and when I use the remote fan, it works at a shorter distance, but when the lamps are off, the remote works at a longer distance. What do fluorescent lamps do that affects the operation of the remote?

I expect the fan uses an IR remote control.
The switching of the FL causes IR, optical, or RF pulses, that are picked up by the IR receiver. That makes it less sensitive because the noise floor is higher.
 

Thread 'The Effect of Linear and Rotational Motion on Measured Weight'

Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...

Thread 'Coulomb gauge implies instantaneous radial electric field?'

Scalar and vector potentials in Coulomb gauge Assume Coulomb gauge so that $$\nabla \cdot \mathbf{A}=0.\tag{1}$$ The scalar potential ##\phi## is described by Poisson's equation $$\nabla^2 \phi = -\frac{\rho}{\varepsilon_0}\tag{2}$$ which has the instantaneous general solution given by $$\phi(\mathbf{r},t)=\frac{1}{4\pi\varepsilon_0}\int \frac{\rho(\mathbf{r}',t)}{|\mathbf{r}-\mathbf{r}'|}d^3r'.\tag{3}$$ In Coulomb gauge the vector potential ##\mathbf{A}## is given by...

Thread 'Simple thought experiment with Stefan-Boltzmann law: energy'

Dear all, in an encounter of an infamous claim by Gerlich and Tscheuschner that the Greenhouse effect is inconsistent with the 2nd law of thermodynamics I came to a simple thought experiment which I wanted to share with you to check my understanding and brush up my knowledge. The thought experiment I tried to calculate through is as follows. I have a sphere (1) with radius ##r##, acting like a black body at a temperature of exactly ##T_1 = 500 K##. With Stefan-Boltzmann you can calculate...
