Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.

Ethan was driving, moving at 16.0 m/s, approaching the open window of Khuslen who was experimenting with a frequency generator on his phone. If Khuslen's phone was generating a tone of 452 Hz, what was the frequency perceived by Ethan? Assume the speed of sound to be 343 m/s.
For testing purposes, a musical instrument manufacturing company creates a device so that when you blow into one end with your instrument, sound comes out the other end in opposite directions. A sound technician uses a whistle and generates sound waves with a frequency of 280 Hz. The waves travel in opposite directions in a sound studio, are reflected by end walls, and return. The studio is 43.0 m long and the whistle is located 14.0 m from one end. What is the phase difference (in degrees) between the reflected waves when they meet at the source of the sound? The speed of sound in air is 343 m/s. 17044.898X See if you can determine the path difference and the wavelength, and then express the path difference in terms of the wavelength.
