Simple Laser Diffraction Experiment at Home: Long story short: You will learn how to observe interference patterns at home (using the cheapest laser point you got). I will also teach you how to use your laser to measure tiny objects, like the width of your hair!!
Reflection, Refraction, Diffraction introduces students to these three properties of light. Students will discover how light behaves differently when it encounters different kinds of objects. If it reaches a very smooth object, it reflects. If it passes through one medium to another, it refracts.
BENDING LIGHT – DIFFRACTION WHAT HAPPENS WHEN LASER LIGHT PASSES AROUND AN OBJECT? IF THE OBJECT IS A HAIR, CAN YOU USE THE PATTERN OF DARK AND BRIGHT SPOTS TO MEASURE ITS DIAMETER? The calculations in this lesson require that children understand and can manipulate numbers in scientific notation.
You can easily demonstrate diffraction using a candle or a small bright flashlight bulb and a slit made with two pencils. The diffraction pattern—the pattern of dark and light created when light bends around an edge or edges—shows that light has wavelike properties.
diffraction pattern. Accompanying sheet: Diffraction Patterns Shine the laser light through the fabric. What sort of pattern do you see? How does the pattern change when you stretch the fabric horizontally? What about when you stretch it vertically?
Diffraction patterns can include dots, rings and strips and the pattern tells you information about the object. We’ll use diffraction to measure CD and DVD track spacing, the width of your hair and other small objects. WIRE MESH Activity. Aim: To use diffraction to measure the gap space in two different pieces of wire mesh. Examining the Mesh.
