1. (a) Two point sources are generating periodic waves in phase. A point on the fourth nodal line is 25.0cm from the source and 39.0cm from the farthest source. Construct a sketcth of the physical situation and determine the wavelength.

(b) Two point sources, 3.0cm apart,are generating periodic waves in phase. A point on the third antinodal line of the wave pattern is 10cm from one source and 8.0cm from the other source. construct a sketch of the physical situation and determine the wavelength of the waves.

Assume that there are two point sources of spherical acoustic waves along the x-axis at both x=a and x=-a and that they both have wavelength lambda naught and are in phase with each other. Given that far away from the origin in the xy plane, the first pair of nodal lines makes an angle theta with the y-axis and that theta is small, what is theta?

Two in-phase sources of waves are separated by a distance of 3.68 m. These sources produce identical waves that have a wavelength of 5.28 m. On the line between them, there are two places at which the same type of interference occurs. (a) Is it constructive or destructive interference?

K 2. Point Source Interference Pattern Consider a two-dimensional x-y space in which there are two identical and synchronized point sources located at y=±D/2 emitting waves of wavelength λ. The sources are said to constructively interfere at any location if the phase difference between waves received from the two sources at that location differ by an integral multiple of 2π. Equivalently, the distances from the location to the two sources differ by an integral number of wavelengths. Derive the complete...

PART A Two light waves of the same frequency start out in phase (with amplitudes going up at the same moment), and they interfere having traveled different distances.  What happens if the path difference in the two waves is 1200 nm and the wavelength of the light is 400 nm (blue light)? The waves add in step and the  time-averaged power at that place is 4x that of one wave alone. The waves add in step and the  time-averaged power at that is...
