Two thin convex lenses of focal length f1and f2 are separated by a horizontal distance d (where d<f1,d<f2) and their centers are displaced by a vertical separation Δ as shown in figure.Taking the origin of coordinates O at the center of the first lens, the x and y coordinates of the focal point of this lens system, for a parallel beam of rays coming from the left, are given by:
Answer» Two thin convex lenses of focal length $f_{1} a n d f_{2}$ are separated by a horizontal distance d (where $d < f_{1}, d < f_{2}$ ) and their centers are displaced by a vertical separation $Δ$ as shown in figure. Taking the origin of coordinates O at the center of the first lens, the x and y coordinates of the focal point of this lens system, for a parallel beam of rays coming from the left, are given by:

Two speakers S1 and S2 are derived from the same amplifier and placed at the same distance from x-axis as shown in figure. The speakers vibrate in phase at 680 Hz. A man stands at a point on the x-axis at a very large distance from the origin and starts moving parallel to the y-axis. The speed of sound is 340 m/s. Then, at what angle θ with the x− axis will the intensity of sound drop to a minimum for the first time?
