I Am Fascinated By PhysicsQuick question. Can anyone tell me what 'nu' with a subscripted 'b' refers to in the context of electomagnetic radiation? I saw in a table of photon energies.
I Am Fascinated By PhysicsThe voltage drop across an LED seem to be directly proportional to the colour (energy) of the emitted light. e.g. red LEDs (wavelength c.660nm)have a voltage drop of about 1.8v and blue LEDs (wavelength c.450nm) about 3.3v. If a LED needs 3.3v to... See More »
I Am Fascinated By PhysicsI want you to take a moment to ponder this... Firstly everything around us is made up of atoms, those atoms are made up of even smaller particles but because of how they are arranged they are mostly space, therefore everything "solid" is made of... See More » (1)
