4. In a church choir loft, two parallel walls are 5.30 m apart. The "singers stand against the north wall. The organist faces the south wall, sitting 0.800 m away from it. So that she can see the choir, a flat mirror 0.600 m wide is mounted on the south wall, straight in front of the organist. What width of the north wall can she see? Hint: Draw a top-view diagram to justify your answer.

The figure shows a refracted light beam in linseed oil making an angle of ? = 15.8° with the normal line NN'. The index of refraction of linseed oil is 1.48. a) Determine the angle ?. b) Determine the angle ?'.

A small pin fixed on a table top is viewed from above from a distance of 50cm. By what distance would the pin appear to be raised if it is viewed from the same point through a 15cm thick glass slab held parallel to the table? Refractive index of glass = 1.5. Does the answer depend on the location of the slab?

A student stands dsub0=2.4 m in front of a floor-to-ceiling mirror. Her eyes are hsube=1.53 m above the floor and she holds a flashlight at a distance hsubf=.55 m above the floor. Calculate the angle in degrees that the flashlight makes with respect to the floor if the light is reflected into her eyes.
