Q1. I do not understand why the light has to bend inorder to undergo refraction. My teachers have explained me that, light bends due to the change in velocity. If I change the velocity of a car by half it's original value, I don't find the cars path changing. It does not seem to make sense to me. Why does the light bend?
Q2. Can light be effected by changing magnetic field.
Q3. What do you mean by amplitude of light? In the wave nature of light. Does it have to do with the magnitutes of the max. Electric field and max. Magnetic field?
Q4. Applying energy conservation in the wave nature of light. Suppose I take two really small areas. If I have a light beam with it's electric field and magnetic field at their maximum let that energy be k. After a time t/4 seconds (t being equal to 1/f, where f is the frequency of light) If I try to find the energy using the classical energy density formulas as earlier, I will get 0. I know I am missing something. What is it ?
Q5. If I have an apparatus, and a magical instruments which are very accurate. If I have thick slits (Thick enough to be 1000 times the thickness of light. If the slits are made of conductors (Assuming their atomic sizes are very very very small). If I pass a light through these slits, with distance between the slits being less then the amplitude of the electric field component of light. What will happen?
I am sorry for the grammatical errors. Thank you for all the help and support.
