refection refraction diffraction polarization interference dispersion photoelectric effect
The result of diffraction is the bending of waves around obstacles or through small openings.
Reflection and refraction. (Another is absorption.) (Another of the two is dispersion and interference.) (And another one is diffraction.)
Reflection, or refraction, depending on what causes the change in direction.
Reflection and Refraction
Light demonstrates wave characteristics when it undergoes phenomena such as interference, diffraction, and polarization. These behaviors are consistent with light behaving as a wave rather than a particle.
Reflection, Refraction, Diffraction
refraction, diffraction, reflection there are only 3
refraction, diffraction, reflection there are only 3
To create a Venn diagram to show the relationship between reflection, refraction, and diffraction, you can start by drawing three overlapping circles. Place reflection in one circle, refraction in another, and diffraction in the third. Where the circles overlap, you can show the instances where these phenomena can occur simultaneously, such as in the case of a prism splitting light into a spectrum (involving refraction and diffraction).
We make that assumption from scanty, flimsy evidence. The only indication we have is that radio waves exhibit all the properties of reflection, refraction, diffraction, dispersion, polarization, and interference that are characteristic of waves, and that they all closely match the mathematics of wave motion. Other than that, there's nothing to go on.
There is no evidence to support that conjecture. Except for the facts that electromagnetic energy exhibits reflection, refraction, diffraction, dispersion, constructive interference and destructive interference depending on phase difference, polarization, and inverse relationship between wavelength and frequency. Other than those bits, it's "only a theory".
