What must the path difference between two coherent light sources of wavelength l be for constructive interference to occur at a point where the two waves meet?
a. m/(2λ) where m is an odd integer
b. mλ where m is any integer or zero
c. mλ where m is an odd integer
d. m/(2λ) where m is an even integer
e. mλ where m is an even integer
I've tried c, d, and e and only have one more try.
I know that with destructive interference, the answer is a but cant seem to get the answer and ractional for constructive interference. Thanks.
Since 2mπ = 2πx/ wavelength
=) x = m(wavelength)
Hence option b is correct answer.

2.1.1. Two coherent sources, A and B, of radio waves are 40.0 cm apart. Each source emits waves with wavelength 50.0 cm. Consider points along the line between the two sources. At what distances from A, if any, is the interference (a) constructive, (b) destructive? 2.1.2. A coherent source of monochromatic light of unknown wave- length shines on double slits separated by 0.40 mm. Bright spots separated by 0.80 cm appear on a screen 5.0 m away. What is the...
Two in-phase sources of waves are separated by a distance of 3.77 m. These sources produce identical waves that have a wavelength of 5.25 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? (b) and (c) Where are these places located (the smaller distance should be the answer to (b))?
1. Please answer the following questions regarding coherent lights: A. B. C. What makes two light sources coherent? the same frequency the same frequency, and maintaining a constant phase difference the same amplitude, and maintaining a constant phase difference the same frequency and amplitude Monochromatic coherent light shines through a pair of slits. If the wavelength of the light is decreased, which of the following statements is true of the resulting interference pattern? The distance between the maxima stays the...
Two point sources of sound are coherent and in phase and emit sound at a wavelength of 1.6 m. They are both located on the x-axis, one at x = 1 m and the other at x = -1 m. Constructive interference occurs on the x-axis at what positive value of x?
(c) In terms of the light rays that "form” the image, what is the difference between a real and a virtual image? (d) Where is an image located if it is viewed with a relaxed eye?

(e) For two coherent waves of equal wavelength, explain the condition on the path length difference for destructive interference. A diagram is required.
Understanding Two-Source Interference Learning Goal: To understand the assumptions made by the standard two-source interference equations and to be able to use them in a standard problem For solving two-source interference problems, there exists a standard set of equations that give the conditions for constructive and destructive interference. These equations are usually derived in the context of Young's double slit experiment, though they may actually be applied to a large number of other situations. The underlying assumptions upon which these...
