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.)

A certain kind of glass has an index of refraction of 1.650 for blue light of wavelength 430 nm and an index of 1.615 for red light of wavelength 680 nm. If a beam containing these two colors is incident at angle of 30.00 % on a piece of this, what is the angle between the two beams inside the glass?
