6 x 2 x 2450000000 = 29400000000 cm/s. How to: - Take the turntable out of the microwave. Turntable (does that have a name? Now you know the wavelength you need to know the wave frequency. Speed of light = wavelength x frequency.
Microwaves are a type of electromagnetic radiation, just like. This is equivalent to 294, 000, 000 metres per second. Measuring the distance between melted spots gave you half a. wavelength. In centimetres, z will be in centimetres per. You need the chocolate. Was your answer close to the speed of light? The distance between each melted spot should be around 6. centimetres. Take the chocolate out of the microwave - carefully! Spots is half a wavelength. Pretty close to the speed of light! All you need is a microwave, ruler, bar of chocolate. 45 gigahertz expressed as. Distance between two melted spots of chocolate x 2 x. 299, 792, 458 metres per second.
A wave will move up and down 2. Microwaves also travel at the speed of light. 45 gigahertz in most microwaves. Work out the wavelength of the microwaves. Multiply the distance between the spots on the chocolate bar by. When you measure the distance between two melted spots you can. You don't need fancy equipment to.
You're not sure of the frequency. The distance between two melted. Remember E=mc2, Einstein's famous equation? Put a plate upside down over the thing that rotates the. To the speed of light. This means that the microwaves move up and down.
Measure how fast they are travelling, you should get a result close. To stay still whilst you heat it. Heat the chocolate until it starts to melt in two or three. Put your chocolate in the middle of the plate. Multiply that by 2, 450, 000, 000 (2. If your microwave is a standard model, it will have a frequency. You need to multiply the distance by two to get a whole.
This experiment featured on the Null. 45 billion times per second. Now you've satisfied your curiosity, you can eat the chocolate. Check in your microwave manual if. A well deserved reward for you hard work. Hypothesis and Wired. Remember, if you measured the distance between the melted spots. This should take about 20 seconds. What answer do you get for z?
Wave frequency is how many times a wave bounces up and down in one. For now I'm going with.
