how to measure speed of light using microwave. Double this distance to compute a full wavelength. Speed of a Wave c Frequency f x Wavelength L The distance between the melted sections of the marshmallow is in fact L2 because there are two nodes for each wave see animation.
How To Measure The Speed Of Light With Marshmallows Christmas Lectures Light Speed Light Speed from in.pinterest.com
Place the mini-marshmallows in the dish one layer thick. And since many of the suggested experiments also involve chocolate it will be done. Speed of a Wave c Frequency f x Wavelength L The distance between the melted sections of the marshmallow is in fact L2 because there are two nodes for each wave see animation.
Well the speed of light is equal to the frequency times the wavelength.
With one more piece of information the frequency of the waves you will be able to calculate the speed of light. The microwave used in the video produced light waves with a frequency of 2450000000 Hertz or that many cycles per second. If you know how to measure the wavelength of the signal from a microwave oven using a plate of chocolate and you know its frequency around 2500 MHz you can calculate the speed of light. 7628 cm 2 15256 cm.
