# 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?
