The product of the Planck constant and the speed of light is a fundamental value in physics that plays a crucial role in quantum mechanics and theoretical physics. The Planck constant, denoted as h, is approximately 6.626 × 10-34 joule-seconds. The speed of light in a vacuum, represented by c, has a value of about 3.00 × 108 meters per second.
To determine the product of these two constants, you simply multiply them:
h × c ≈ (6.626 × 10-34) × (3.00 × 108)
This results in approximately 1.987 × 10-25 joule-meters. This value is significant in various equations and theories, particularly in the realm of quantum field theory and cosmology. It helps to define relationships between energy, mass, and wavelength, illustrating the inherent connections between the fundamental forces of nature.
