• Humans see light as an electromagnetic wave that causes them to see. In a vacuum, light moves at a constant speed, but in different medium, it moves at variable rates.
• The rules of physics are used by physicists to examine light and its qualities.
• Infrared (heat), ultraviolet (sunburns), X-rays (medical), and radio and microwaves are examples of electromagnetic waves that humans encounter or utilize .

• In many branches of physics, the universal physical constant c, or the speed of light in vacuum, is crucial.
• 299792458 metres per second is the exact number (about 300000 kilometres per second, or 186000 miles per second).

• c is the highest limit for the speed at which ordinary matter, energy, or any signal conveying information may move across space, according to special relativity.
