A hologram uses diffraction to create a 3D image by diffracting light waves off the holographic plate, resulting in an interference pattern that forms the image. Reflection is not the primary mechanism used in holograms.
Diffraction and reflection are both phenomena related to the interaction of waves with obstacles or surfaces. Diffraction involves the bending of waves around obstacles, while reflection involves the bouncing back of waves off a surface. Both processes illustrate how waves can be altered by encountering different mediums or boundaries in their path.
Diffraction. It occurs when waves encounter an obstacle or aperture and bend around it, spreading out into the region behind the barrier.
The result of diffraction is the bending of waves around obstacles or through small openings.
Holograms can be detected using light filters by observing changes in color or brightness as the filter is applied. The filter may reveal hidden elements or patterns within the hologram that are not visible to the naked eye, helping to authenticate the hologram's validity. Different filters, such as polarizers or diffraction gratings, can be used to manipulate the light and enhance specific features of the hologram.
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).
Reflection, or refraction, depending on what causes the change in direction.
reflection is the only process in which the wave does not continue moving forward.
The diffraction of light in the real life can be seen as a rainbow pattern on a DVD or CD. The closely spaced tracks function as diffraction grating. A credit card's hologram is another example diffraction light application in real life. The grating structure on the card produces the desired diffraction pattern.

The examples of reflection of water waves include reflection, refraction and diffraction.

A hologram is a photographic image that is 3-dimensional and appears to have depth. Holograms work because they have two 2-dimensional pictures, so the "object" can be seen 3-dimensionally. This requires the use of light and a single wavelength to do so. You must use a laser. The reflection makes the hologram viewable in normal lighting like in your home. Two laser beams and a photographic plate must be used for a hologram to work.
