No, the velocity of light cannot be calculated directly by a person using simple tools or measurements. The speed of light in a vacuum, denoted by 'c', is a fundamental constant of nature that has been determined through experimental methods and theoretical models.
One of the most famous experiments conducted to measure the speed of light was the Michelson-Morley experiment in the late 19th century. However, this experiment aimed to detect the motion of Earth through the hypothetical luminiferous aether rather than directly calculating the speed of light.
Today, the value of the speed of light is defined to be exactly 299,792,458 meters per second in the International System of Units (SI). This definition provides a precise value for the speed of light and serves as the foundation for many scientific and technological applications.
In summary, the velocity of light is not something that can be easily calculated by an individual without the use of sophisticated experimental setups and scientific knowledge. It is a well-established constant in physics that has been determined through extensive scientific research and experimentation.
