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:

The diagram shows a laser being used to display an image recorded on a holographic plate.

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?

  • ARefraction
  • BReflection
  • CDiffraction
  • DPolarization
  • EBeat frequency

Q4:

The diagram shows some apparatus used in holography, including a cylindrical object.

Which of the following is true of the path lengths of the beam paths ABC and ABD?

  • AThe path lengths are the same.
  • 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?

  • AVirtual image B
  • BBoth virtual images simultaneously
  • CEach virtual image would alternate.
  • DNeither virtual image
  • EVirtual image A

  • BIII
  • CVII
  • DIV
  • EII
