This means that a wave will move up and down 245 billion times per second. This tells us that the speed of light is 294000km per second. Calculate the speed of the microwaves using the wavelength measured and frequency from the oven label.
Now since the speed of light is equal to the wavelength times the frequency we can figure out the speed of light.
The speed of light called c is given by this formula. Speed of light 2 x distance between melted spots x frequency of microwave The actual speed of light is 300 x 1010 cms. This tells us that the speed of light is 294000km per second. 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.
