A whispering gallery is a room in the shape of an elliptic reflector. If a source of sound is placed at one focal point of an elliptic reflector, the sound is reflected through the other focal point. If one person speaks at one focal point, then another person at the other can hear sounds as faint as a whisper. If the whispering gallery is based on the ellipse 1-² 2 = 1 + 625 576 The people will have to stand at each focus which is Blank 1 Blank 1 Add your answer units from the center. (HINT: find c).
