Y is the angle between the waves and a plane through the slit perpendicular to the screen. ✓ λ is the wavelength of the light source. Suppose you have the distance and ray angle and need to know the wavelength that creates a desired phase angle. You would manipulate the equation to solve for λ : Again, all you need to do is plug in the other known variable values and you have your answer. Finding lengths and angles with trigonometry Trigonometry is a portion of mathematics based on the special properties of the right triangle.

Expanding Your Understanding of Optics The fundamental principles of optics can tell you what will happen with light in different situations, but making something useful with these principles isn’t so easy. Applications of optics, including optical systems, combine two or more optical phenomena to create a desired output. Most applications of optics require knowledge about how optical principles work together in one system; making optical systems requires careful thought to make sure that the light behaves in the way you want it to when you look at the final result, whether that’s light from a particular source (such as a light bulb or laser) or an image from a telescope or camera.

Say you know everything about this example but the value of n2, the second index of refraction. You can solve for that value by dividing both sides of the equation by the sin θ2; with a little reorganization of the equation, you end up with Now you can plug in the known quantities and get your answer. indd 17 6/27/11 2:01 PM 18 Part I: Getting Up to Speed on Optics Fundamentals Another example of useful algebra in optics has to do with the two-slit diffraction pattern. In high school physics class, you may have seen a demonstration where your teacher projected light through a very small slit; the light then passed through two more narrow slits parallel and equidistant from the first and then fell onto a screen some distance away, creating a pattern of light and dark vertical lines on the screen.
