Webb24 juli 2024 · The first is c = νλ where c = the speed of light in vacuum (3.00 x 10 8 m/s), ν = frequency and λ is wavelength. The second is E = hν where E = energy, h is a special constant called Planck's constant (6.63 x 10 -34 J. s) and ν is again frequency. The second equation tells us that frequency is proportional to energy. Webb27 mars 2024 · f = 3E9 m/s/4.50E-7 m = 666.2E12 Hz = 666.2 THz. Multiply the frequency by Planck's constant: E = h × f = 666E12 Hz × 6.626 m²·kg/s = 4.41E-19 J. Divide this …

WebbE = hf, so f = E/h. Hence, f = 1 eV/6.63 x 10-34 Joule-sec x (1.6 x 10-19 Joule / 1 eV) = 2.41 x 10 14 sec-1 or 2.41 x 10 14 Hz ( Hz means 1/sec). This frequency is in the infrared range, ... Note how we multiplied by the conversion factor between Joules and eV to make those units cancel so that we could express the answer in inverse seconds. 2 ... Webb5 nov. 2024 · Sound Intensity. Sound intensity can be found from the following equation: I = Δ p 2 2 ρ v w. Δp – change in pressure, or amplitudeρ – density of the material the sound is traveling throughv w – speed of observed sound.Now we have a way to calculate the sound intensity, so lets talk about observed intensity. fever low blood pressure
