Lesson Worksheet: Holography Physics
In this worksheet, we will practice describing how the phase differences of coherent light waves can be used to produce three-dimensional images.
Q1:
If a holographic plate is broken into pieces and a laser is used to view the image contained on one of the pieces, which of the following would the image show?
- AThe image that was contained on the whole of the plate but at a lower resolution
- BAn interference pattern
- CNothing
- DA part of the object that had not been scanned by the object beam when the holographic image was formed
- EA part of the object of a size proportional to the size of the piece of the plate
Q2:
The diagram shows a laser being used to record a holographic image of a cylindrical object and then to display the image recorded on the holographic plate. Which of the virtual images would be observed by a viewer at the position shown?
- AVirtual image B
- BEach virtual image would alternate.
- CVirtual image A
- DNeither virtual image
- EBoth virtual images simultaneously
Q3:

Which of the following wave phenomena occurs at the point labeled I in the diagram?
- APolarization
- BRefraction
- CReflection
- DDiffraction
- EBeat frequency
Which of the following wave phenomena occurs at the points labeled II and III in the diagram?

- BABD is longer than ABC.
- CABC is longer than ABD.
Which of the following is true of the path lengths of the beam paths AbcC and AbdD?
- AThe path lengths are the same.
- BAbcC is longer than AbdD.
- CAbdD is longer than AbcC.
Q5:
The diagram shows some apparatus used in holography, including a cylindrical object. Which of the following are the components labeled V and VI?
- AMirrors
- BConvex lenses
- CBeam splitters
- DConcave lenses
- EHolographic plates
Q6:
The diagram shows some apparatus used in holography, including a cylindrical object. Which of the following is the apparatus used for?
- AViewing a recorded hologram of an object
- BRecording a hologram of an object
- CBoth recording and viewing a hologram of an object
Q7:
A laser used in holography emits a beam that travels symmetrically about the optical axis of a concave lens, as shown in the diagram. Which of the following most correctly explains why the beam diverges when it passes through the lens?
- AThe beam has a nonzero width, so the parts of it on either side of the optical axis are refracted away from the axis.
- BThe light in the beam is scattered.
- CThe light beam produces emissions of secondary light beams from the lens material.
- DThe beam does not pass exactly through the optical axis; some offset error is unavoidable, and the beam passes slightly to one side of the axis.
- EThe light in the beam is diffracted.
Q8:
The diagram shows a laser being used to record a holographic image of a cylindrical object and then to display the image recorded on the holographic plate. Which of the virtual images shown would be observed by a viewer at the position shown?
