Now since the speed of light is equal to the wavelength times the frequency we can figure out the speed of light. When you consider how difficult it was to measure the lines of melted cheese this is pretty much spot on. Hertz the unit for frequency is the name we give to inverse seconds or 1 seconds.
Now since the speed of light is equal to the wavelength times the frequency we can figure out the speed of light.
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. Quite close to the actual figure of 299552km per second within 2 anyway. The speed of light called c is given by this formula. This tells us that the speed of light is 294000km per second.
