Binoculars and periscopes use prisms instead of mirrors to reflect light. How does this happen? Draw a sketch.
When hot air rises above a stove top, objects behind it appear to shimmer. What causes this?
In Fig.1, which refractive index is greater, na or nb? How would the figure appear if it was the other way round? Draw a sketch.
PART 1 ANALYSIS
NOTE: SHOW ALL YOUR WORK WHERE CALCULATING IS INVOLVED
What is the relationship between the angles of incidence and reflection?
What is the relationship between the object and image distances for a plane mirror?
Plot a graph of sin θa (y axis) vs. sin θb (x axis) and, from the slope, calculate the refractive index of the rectangular block. (The refractive index of air is 00029 which you can approximate to 1.0).
[Place graph here – 1 TOTAL]
Calculate the refractive index of the semicircular block.
What happened to the refracted ray when the angle of incidence was larger than the critical angle?
What happened to the intensity of the reflected ray when the angle of incidence was larger than the critical angle?
