The energy and wavelength of electromagnetic radiation are inversely related. This relationship is described by the equation:
E = hc/λ
where: E represents the energy of the electromagnetic radiation, h is Planck's constant (approximately 6.626 x 10^-34 joule-seconds), c is the speed of light in a vacuum (approximately 3.00 x 10^8 meters per second), and λ (lambda) represents the wavelength of the radiation.
According to this equation, as the wavelength (λ) of electromagnetic radiation increases, the energy (E) decreases, and vice versa. In other words, longer wavelengths correspond to lower energy, while shorter wavelengths correspond to higher energy. This relationship is a fundamental principle of quantum physics.
