If the frequency is in megahertz you will then need to multiply by 1 million (1,000,000) and if using gigahertz multiply by 1 billion (1,000,000,000). Web in the 17th century, galileo attempted to measure the speed of light by timing how long it took for light to travel between two hills. Its significance is far broader than its role in describing a property of electromagnetic waves.
