Plank's Constant is a physical constant that relates the energy of a photon to its frequency. It is denoted by the symbol "h" and has a value of 6.626 x 10^-34 joule seconds.
To find the wavelength using Plank's Constant, you can use the formula: wavelength = h / (mass x velocity). Mass and velocity must be in units of kilograms and meters per second, respectively.
Plank's Constant is used in calculations involving wavelength because it helps us understand the relationship between energy and frequency of a photon. This is important in many fields of science, including quantum mechanics and spectroscopy.
The units for Plank's Constant are joule seconds (J·s) in the International System of Units (SI). Some other commonly used units include eV·s and erg·s.
Yes, Plank's Constant has been measured with high precision using a variety of experimental methods. In 2019, the International System of Units redefined the kilogram in terms of Plank's Constant, further solidifying its accuracy and importance in modern science.
