Chemistry Worksheet and Answers Wavelength, frequency, & energy of electromagnetic waves. C = λν. C = 3.00 x 108 m/s. E = hν h = 6.626 2 x 10-34 J-s (or J/Hz) 1. What is the wavelength of a wave having a frequency of 3.76 x 1014 s-1?
Formulas and Constants: f = c/λ E = hf. f = frequency. c = speed of light (3.0 x 108 m/s) λ = wavelength. E = energy h = Planck’s constant (6.6262 x 10-34 J•s) 1. Calculate the λ given the frequency of radiation is 5.10 x 1014 hz. 2. Calculate the frequency of red light with λ = 6.50 x 10-7m.
Speed /Frequency / Wavelength. Period:______. Equation: Speed of all Electromagnetic Spectrum Waves (c) = 3.0 x 108 m/s. c (m/s) = ν x λ ν (Hz) = c ÷ λ λ (m) = c ÷ ν. Speed “c”. (m/s) Frequency “ν” Wavelength (Hz) “λ” (m) 1. Violet light has a wavelength of 4.10 x 10-12 m.
Wavelength, Frequency, and Energy of Electromagnetic Waves. Show ALL equations, work, units, and significant figures in performing the following calculations. Identify the type of radiation in each problem. (Use your electromagnetic spectrum)
Calculate the energy of a gamma ray photon whose frequency is 5.02 x 1020 Hz? 11. Calculate the energy of a photon of radiation with a wavelength of 6.4 x 10 -7 m.
J·s and the variable ν represents the frequency in 1/s, s-1, or Hz (Hertz). This equation allows the calculation of the energy of photons, given their frequency. If the wavelength is given, the energy can be determined by first using the light equation (c = νλ) to find the frequency, then using Planck’s equation to calculate energy. ν =
