Answer #1

When light experiences a phase change, the wave velocity changes.

For 3rd order Young's double slit experiment, the number of bright interference fringe = 3 - 1 (-1 is for central spot)

= 2

    Suppose Young's double slit experiment is performed in air using red light and the interference pattern is shown on a screen. You then submerge the entire setup into water. What happens to the interference pattern? It disappears. The bright fringes are farther apart. The bright and dark fringes stay in the same locations but the contrast is reduced. No change happens in the interference pattern. The bright fringes are closer together.

    Question 5: How would dust and oil on the glass plates affect the results? EXPERIMENT 10 THIN FILM INTERFERENCE Light from a monochromatic source is shined downward on two glass plates that are separated at one end by a hair. Light that is reflected from the top and bottom surfaces of the wedge-shaped thin film of air undergoes interference, and a series of dark and light lines are seen. By counting the number of dark or light lines over a...

    In our study of thin film interference we have seen that when light strikes a surface with a different index of refraction the incident light splits into 2 reflected beams and 2 refracted beams. The total phase difference between any two interference. This will to the two general cases described below. For each case give several applications of this situation adjacent beams can lead to either constructive or destructive 17 Case I: Beams 1 & 2 interfere constructively (maximum reflection.,)...

    To understand the cause of constructive and destructive interference for the double-slit experiment, and to explain how the interference pattern depends on the parameters of the emitted waves. For this tutorial, use the PhET simulation Wave Interference. This simulation allows you to send waves through a variety of barriers and look at the resulting interference patterns. Start the simulation. You will see three possible selections: Waves, Interference, and Slits. To change between simulations at any point, select the desired simulation...
