Find the lowest frequency for which destructive interference
Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves in phase. Speaker B is 2.00 m to the right of speaker A. Consider point Q along the extension of the line connecting the speakers, 1.00 m to the right of speaker B. Both speakers emit sound waves that travel directly from the speaker to point Q. a) What is the lowest frequency for which constructive interference occurs at point Q? b) What is the lowest frequency for which destructive interference occurs at point Q?
Phenomenon of interference of water waves 1. Arrange two identical adjacent pins (S1 and S2) vibrating in a ripple tank with the same frequency. 2. In the figure S and S ar
A 12 volt battery is associated across a series combination of two capacitors C1 and C2. The capacitance of C2 is double that of C1.

Q. If 6.25 X 10 18 electrons flow through a given cross-section in unit time, find the current. Solution: Current I = q / t = ne / t = (6.25 X 10 18X 1.6 X 10 -19) / 1 = 1 A
