### Phasor Diagram Analysis**Description:**The diagram illustrates a basic setup for analyzing wave interference from three point sources of light. These sources are positioned linearly a distance \( D \) from a screen. At point \( P \) on the screen, directly in front of the sources, the waves are in phase. This is depicted by a phasor diagram showing three phasors \( A_1 \), \( A_2 \), and \( A_3 \) combined to form a single resultant phasor \( A_{\text{net}} \).#### Phasor Diagram Explanation:- **Phasors \( A_1 \), \( A_2 \), \( A_3 \):** These represent the amplitude of each wave individually, all in phase at 0°.- **Resultant Phasor \( A_{\text{net}} \):** The net amplitude \( A_{\text{net}} = 3A \), where \( A \) is the amplitude of each individual phasor. This occurs because the difference in phase between adjacent phasors is 0°.### Tasks:#### (a) Phasor Diagram with 45° Phase Difference- **Diagram Needed:** Sketch a new phasor diagram where each adjacent phasor has a 45° phase difference.- **Details to Include:** An arrow indicating \( A_{\text{net}} \) with numerical angle \( \theta \) from the first phasor.#### (b) Phase Difference of 90°- **Action:** Repeat step (a) for a 90° phase difference.#### (c) Phase Difference of 120°- **Action:** Repeat step (a) for a 120° phase difference.#### (d) Phase Difference of 180°- **Action:** Repeat step (a) for a 180° phase difference.#### (e) Phase Difference of 240°- **Action:** Repeat step (a) for a 240° phase difference.This exercise helps in understanding the superposition principle and interference patterns resulting from different phase differences.

The diagram below illustrates the phenomenon of "missing orders" in the interference pattern made by a double slit. Some orders are missing (that is, there should be a bright fringe but there isn't) because: "Missing orders" Select one: a. Light reaching the screen that passes through different parts of each slit interferes destructively, even though light from the two slits interferes constructively O b. Light reaching the screen from the two slits interferes destructively, even though light that passes through different parts of each slit interferes constructively
