Two speakers are driven by the same oscillator whose frequency is f. They are located a distance d from each other on a vertical pole. A man walks straight toward the lower speaker in a direction perpendicular to the pole, as shown in figure.
(a) How many times will he hear a minimum in sound intensity?
(b) How far is he from the pole at these moments? Let v represent the speed of sound, and assume that the ground does not reflect sound.
In a young's double slit interference pattern, the fringe width is 0.1 mm. Determine the fringe width if the wave length of light is increased by 10% and the distance between the s

Describe Kirchoff's Voltage Law? Ans. It describe, " the sum of the Voltage drops around a DC series circuit same to the applied voltage or source. E = E 1 + E 2 = E 3 .
Ferromagnetic materials exhibit magnetic behaviour similar to ferromagnetism below a critical temperature, known as curie temperatures. Above which it turns out to be paramagnetic.
