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.

An electric current through hydrogen gas produces several distinct wavelengths of visible light. What are the wavelengths of the hydrogen spectrum, if they form first-order maxima at angles of 24.2°, 25.7°, 29.1°, and 41.0° when projected on a diffraction grating having 10,000 lines per centimeter? Explicitly show how you follow the steps in Problem-Solving Strategies for Wave Optics
Does the fact that the light flash from lightning teaches you before its sound prove that the speed of light is extremely large or simply that it is greater than the speed at sound? Discuss how you could use this effect to get an estimate of the speed of light.
A certain kind of glass has an index of refraction of 1.650 for blue light of wavelength 430 nm and an index of 1.615 for red light of wavelength 680 nm. If a beam containing these two colors is incident at an angle of 30.00 on a piece of this glass, what is the angle between the two beams inside the glass?
The wavelength of light changes when it passes from one medium into another. Suppose green light at 550.0 nm passesfrom air into glass (n = 1.5). a. What is its wavelength in glass? b. What is its frequency? c. Do you see the same color in both media?
The speed of a water wave is described by v=gd, where d is the water depth, assumed to be small compared to the wavelength. Because their speed changes, water waves refract when moving into a region of different depth. (a) Sketch a map of an ocean beach on the eastern side of a landmass. Show contour lines of constant depth under water, assuming a reasonably uniform slope. (b) Suppose waves approach the coast from a storm far away to the northnortheast. Demonstrate that the waves move nearly perpendicular to the shoreline when they reach the beach. (c) Sketch a map of a coastline with alternating bays and headlands as suggested in Figure P34.26. Again make a reasonable guess about the shape of contour lines of constant depth. (d) Suppose waves approach the coast, carrying energy with uniform density along originally straight wave fronts. Show that the energy reaching the coast is concentrated at the headlands and has lower intensity in the bays. Figure P34.26
In a laboratory accident, you spill two liquids onto different parts of a water surface. Neither of the liquids mixes with the water. Both liquids form thin films on the water surface. As the films spread and become very thin, you notice that one film becomes brighter and the other darker in reflected light. Why?
Calculate the wavelength of light that has its third minimum at an angle of 30.0° when falling on double slits separated by 3.00 m. Explicitly, show how you follow the steps in Problem-Solving Strategies for Wave Optics.
A beam of light always spreads out. Why can a beam not be created with parallel rays to prevent spreading? Why can lenses, mirrors, or apertures not be used to correct the spreading?
Why does the wavelength of light decrease when it passes from vacuum into a medium? State which attributes change and which stay the same and, thus, require the wavelength to decrease.
Diffraction spreading for a flashlight is insignificant compared with other limitations in its optics, such as spherical aberrations in its mirror. To show this, calculate the minimum angular spreading of a flashlight beam that is originally 5.00 cm in diameter with an average wavelength of 600 nm.
You are working for an optical research company during a summer break. Part of the apparatus in one particular experiment is shown in Figure 34.7b. In fact, the experimenter used this text book to set up this part of the experiment, and also used the result in the What If? section to determine the angular change in direction of the light beam: =3602 (1) The experimenter is constantly grumbling that the measuring device to determine the angle on the inside of the mirrors is constantly getting in the wav of the light beam and making his life difficult. You quickly draw Figure P34.5 and then say. Then why dont you use the measuring device to measure the angle outside the mirror, and then your device wont get in the way of the light? The experimenter, who has never thought of this, tries to save face and says to you. Well, Smarty, then tell me how angle depends on angle ! You provide him the answer quickly. Figure P34.5
Explain how microscopes can use wave optics to improve contrast and why this is important.
