First, let me see if my facts are straight. White coloured objects reflect more light of ALL frequencies than black coloured objects, including infrared, etc. Hence a white coloured object is cooler than a black coloured object. If visible light was the only factor, a blue room would be cooler...
Thanks. So, in the same way, particles like electrons are particles only when they interact with something else(other particles, say a proton in this case) and otherwise they can be considered to be waves? So the wavelength here does not mean the particle rides along a 'loop' but rather it...
Ok, so I have many questions about light. My basic understanding can be seen here:

My first question is, consider transverse waves in water. As the wave moves out, the water molecules move up and down forming the crests and...
Okay so suppose in a second at a point in space the field oscillates from maximum to minimum back to maximum once in a second if the frequency is the same but the intensity is more that same point will have same maximum to minimum back to maximum oscillation but the maximum will be greater?
Okay so in this oscillating fields model higher frequency means faster changing fields, right? And what about more intense light? How is less intense light different from more intense light of the same frequency in this wave model?
Okay so rays are a useful model. In actuality the rays are waves, right? So its actually waves getting refracted and all? Now regarding waves, from what I've read, waves are oscillating electric and magnetic fields. I wanted to know, when a light wave propagates, its actually magnetic and...
Great to get so many replies. I'll try to come to each one one by one. First,
Okay so can all the phenomena such as why a current carrying conductor in an EM field experiences a force, EM induction, etc. be explained using this ultimately? From what I understand now if a test charge moves...
I've got everything about light muddled up now, and I hope I can clear things up in a few posts. First of all, when we learn about light in the classical sense, a 'ray' of light is always mentioned. 'The angle of incidence for a ray of light on a uniform surface is equal to the angle of...
Why doesn't a stationary charge experience a magnetic force? And why does a moving charge produce a magnetic field? From a previous thread on the topic I understand it is from the relativistic interpretation of its electrostatic field. So then why shouldn't it affect a stationary charge?
Okay. So when many rays of light hit the atom at the exact same time, they can only be reflected by electrons which have certain distance between them. What if the ray of light doesn't 'hit' an electron? Is this classical version is wrong? Does the whole electron shell reflect light?
