I didn't really understand the bullet anology... How come a blue photon cannot pass through a less denser milk but can pass through a more dense glass??

Thanks for this post! I think 50% of my question has been resolved. However, I have this question now. Howcome an x-ray photon can pass through the human flesh without any issue but a visible light,say blue photon is reflected back?

how is a light beam different from a group of photons? even a piece of wood takes a photon and reflects in back.. but doesn't transmit it.. why is that so? reflection also involves absorbtion and reemission right? but only in the same direction... why is that so?

ohk.. let me put it this way... I have a glass of water.. and a photon enters it from the left side..and it is absorbed and is reemiited by the first atom in water.. and the process continues until it comes out from the right side of the water column.. why should this happen? And what is the...

Sorry! I didn't understand your reply! What about water? How does light travel in water? that too in straight lines?

Hi, I want to know how light travels through glass. As per my understanding of physics, a photon is absorbed by an electron and the electron goes to a high energy orbit and returns to its original state after a moment and emits another photon. This is how light travels in glass. But how...

Hi Andy, Thanks for your commitment to help others! I have a decently good idea about physics. However, my understanding is limited to the "Principles" of it, and not the exact reason behind those principles. To start with, could you please tell me what an Electro-Magnetic wave exactly...

Hi Andy, Could you please kindly answer the other questions in my earlier posts! Thanks in advance. - Pavan.

Hi Jame, Thanks for your reply. Can anyone explain how prapogation of light through transparent objects work? How can most of the photons travel so perfectly aligned through a solid object? My another question is regarding Polarization. How do polarizors work? - Pavan.

Hi tiny-tim, Thanks for the Reply! Actually I am only 50% satisfied still. What is it that the photon is interacting with? Lets say, I shine some light on a pool of water, what is it that is causing the "normal reaction"? Is the photon bouncing off the nucleus of Hydrogen and Oxygen...

Hi, Can someone please eloborate me why the Angle of Reflection is always same as the Angle of Incidence. I want the explanation at photon and molecular interaction level. Thanks in advance. - Pavan.
