Frequency and wavelength are inversely proportional. This basically means that when the wavelength is increased, the frequency decreas...Wavelength. The distance between two consecutive points in a longitudinal wave is known as wavelength. These consecutive points can be between two compressions or between two rarefactions. Amplitude. Amplitude is the maximum displacement of the particle from its rest point. In a longitudinal wave, the distance from the equilibrium position in the …The above equation is known as the wave equation. It states the mathematical relationship between the speed ( v) of a wave and its wavelength (λ) and frequency ( f ). Using the symbols v, λ, and f, the equation can be rewritten as. v = f • λ. As a test of your understanding of the wave equation and its mathematical use in analyzing wave ... If the photon of the wavelength 150 pm strikes an atom and one of its inner bound electrons is ejected out with a velocity of 1.5 × 10 7 m s – 1, calculate the energy with which it is bound to the nucleus.Learn what is wavelength of light and how to calculate it using the formula. Find out the …A wave is a repeating pattern. It repeats itself in a periodic and regular fashion over both time and space. And the length of one such spatial repetition (known as a wave cycle) is the wavelength. The wavelength can be measured as the distance from crest to crest or from trough to trough. In fact, the wavelength of a wave can be measured as ... Feb 19, 2024 · Wien's law formula. The equation describing Wien's law is very simple: λmax = b / T, where: λmax – Peak wavelength of light; T – Absolute temperature of a black body; and. b = 2.8977719 mm·K – Wien's displacement constant. Although the relation between wavelength and frequency of electromagnetic waves is relatively simple ( λ × f = c ... How to calculate wavelength of a frequency? More about frequency and …A light of wavelength 4800 Å can just cause photoemission from a metal. What is the photoelectric work function for metal in eV? Given: Threshold wavelength = λ o = 4800 Å = 4800 x 10-10 m, speed of light = c = 3 x 10 8 m/s, Planck’s constant = h = 6.63 x 10-34 Js. To Find: Work function of silver = Φ =?
