10 Questions
What does the word 'physical' imply in the context of physical optics?
It is more physical than geometric or ray optics
What does physical optics study in optics?
Interference, diffraction, and polarization
What does the physical optics approximation consist of?
Using ray optics to estimate the field on a surface and then integrating that field over the surface to calculate the transmitted or scattered field
What does coherence theory study in relation to optical communication?
$Quantum noise$
In which frequency range is the physical optics approximation often more accurate in optics than for radio?
$High-frequency$
What is the principle of superposition of waves?
The resultant amplitude at a point is the vector sum of the amplitudes of the individual waves
What happens when a crest of one wave meets a trough of another wave?
Destructive interference occurs
What does interference refer to in physics?
Combining two coherent waves by adding their intensities or displacements with consideration for their phase difference
What did Thomas Young coin in 1801 related to interference?
'Interference'
In constructive interference, what happens when two waves are in phase?
The resultant wave has greater intensity
