Diffraction causes waves to bend around corners and obstacles, spreading out rather than following a straight path. The amount of bending depends on the wavelength of the wave and the size of the obstacle. Diffraction allows waves to reach areas that would be otherwise shadowed by obstacles.

Does it an acceleration if you go around a corner on bycicle?

Yes, when you go around a corner on a bicycle, you are changing your direction of motion, which requires centripetal acceleration towards the center of the curve. This acceleration allows you to turn without skidding off the curve.


What best describes the diffraction of a wave?

The Diffraction of wave is the process of waves going through small objects or obstacles. Diffraction waves spreads out the wave past through some small holes or openings thus basically bending around any object then disperse out.


Can photons diffract?

Yes and no. If you're really talking about just one photon, and say you're going to shoot it a two-slit apparatus and measure where it winds up somewhere beyond the slits, you will only measure one impact position - you won't really see a 'diffraction pattern' because there's only one photon. In some sense, however, there is a diffraction pattern. The bizarre quantum-mechanical 'photon' is described by a wave function that basically can give us probabilities that the photon will hit any point on your detector. This wave function will go partially through both slits, and the resulting wave function on the other side WILL exhibit an interference pattern (!). This diffraction pattern will show itself if you fire photons singly through the slits, i.e. fire one, wait a bit, and fire another. Even though the photons are spaced so that they aren't directly interfering with each other, they will build up a diffraction pattern on the other side because of the diffraction pattern in each photon's individual wave function.


What do you understand by diffraction?

When a wave goes past an obstacle it is slightly bent into the area that should be in shade (the classically forbidden zone), this is also seen at a slit, when the light is spread out. This effect is appriciable when the object is approximately the same sive as the wavelength. This can only be explained using Quantum Electrodynamics. If a screen is placed behind a slit the light makes a larger band than would be expected this is because each photon of light as to be considered to have taken every possible path from the source to the screen. Each path as a probability amplitude associated with it. The probabilities are added in a strang way the lenghth of the probability shown as an arrow are spun at the same rate as the waves frequence these are added by measuring the length from one arrow head to the other if both tails are rotating around the same centre. If both arrows where pointing in the same direction then the probability would be zero, if both arrows where pointing in opposite directions then the probability is squared. Without going into to much detail, the smallness of the slit stops some of the probability amplitude being cancelled out in the forbidden zone.


What happens when the ball bounces of the corner flag and back onto the field of play?

If the ball bounces off the corner flag and remains on the field of play without going out of bounds, the game continues. The corner flag is considered part of the field, so the ball is still in play. Players can continue to play the ball normally.
