This means that a wave will move up and down 245 billion times per second. The frequency f wavelength l and wave speed v are related by the equation. You can measure the speed of light by melting cheese chocolate or even marshmallows in your microwave.
So this means that if the wave has a frequency of 100 Hz it will travel its wavelength 100 times in a second.
In my example that gives us a wavelength of 7628 cm 2 15256 cm Now since the speed of light is equal to the wavelength times the frequency we can figure out the speed of light. So if you have measured 6cm and your oven operates at 2450 MHz then your measured speed of light is 012 x 2450000000 294000000 metres per second. To find the wavelength of the microwaves we multiply by two. Frequency hz is some sort of vibration occurs during a particular period of time as either in a sound waves or in an electromagnetic field.
