Introduction When waves momentarily overlap, they temporarily add Their amplitudes without affecting the original waves. This interference can be seen when two wave sources are used and their overlaps viewed. When waves strike a barrier with one or more openings, some of the energy will bend around the openings and spread out. This is known as diffraction. The interference pattern that results is symmetrical and consists of light and dark regions. The bands of constructive interference are referred to as moximo {single=maxin1um]. Wave Interference Procedure: PhETStrnuiot'ions >Piay With Sims >Physies 2~Sound' and Waves 3 Wave Interference And piay start to run the simulation. Choose \"interference\" in the options screen. Pieose note the waves take some time to settie out and show good grophs be patient! Part 1: Wave Interference Simulation Click on Laser Light using the controls on the right side to show light emission from light sources. First, start only one of the ligh sources to run a single-light source experiment. - Observe the pre-set wavelength of red light and then move the wavelength slider to cyan or blue light. Comment on the actual wavelength of blue light versus red light. - Return the wavelength slider to red and add the screen to show how the light would look if viewed on a screen. Click on the \"screen\" button to add the screen. - Add a second light source by clicking on the button and view the interfering waves and the pattern they create on the screen. I Sketch the pattern
