Measuring The Speed Of Light
Have you ever wondered how fast does light travel ? We can measure the speed of light in our home using just our home appliances through a simple(and tasty !!) activity. Item List For this you will be needing: 1. A microwave 2. A bar of chocolate ( eggs work too!!) 3. A ruler 4. and a calculator. Principle A Microwave oven as the name suggests uses microwaves to heat our food. These microwaves are a part of the Electro-Magnetic spectrum and lie between Radio Waves and Infrared Waves. The interesting part is that these micro waves travel at the same speed as that of light. Viola! Calculating the speed of these micro waves would give us the speed of light. Now thankfully we have a handy equation to calculate this :- Speed of Microwaves (Light) = Wavelength ( Ξ») x Frequency ( Ξ½ ) Experiment Frequency - You may find this at the back of your microwave (usually 2450 MHz) o...
