Activity 2: Calculating Wavelength, Frequency, and Energy of EM Waves Objective: Solve problems involving the wavelength, frequency, and energy of an EM wave. Procedure: 1. Keep in mind that the speed of all types of electromagnetic waves is c, which is equal to 3.0 x 10# m/s. 2. To solve for the frequency, use the formula: 3. To solve for the wavelength, use the formula: 2 =7 4. To solve for the energy, use the formula: E = hfor E = h= where h is the Planck's constant which is equal to 6.626 x 10-34 J.s. 5. Use GUFSA (given, unknown, formula, substitution, answer) pattern. 6. Take note that the unit of the wavelength should be in meters (m) and the frequency is in (cycle/s or Hz). The unit of energy (E) is Joule (J). 7. The first problem is already solved for you. Use it as your guide in answering the remaining problems. Write your answers on a separate sheet of paper.Guide Questions: 1. A radio wave is travelling in space and has a wavelength of 2.0 x 103 m. (A) What is the frequency of the wave? (B) How much energy does it carry? Given: (A) Substitution: (B) Substitution: 1 - 2.0 x 103 m 3.0 x 10 c - 3.0 x 108 3.0 x 10# f=. 20 x 10 E = 6.626 x 10-14 J . m/s 2.0 x 10 Unknown Answer: Answer: f - - Hz f = 150,000 Hz or E = 9.9 x 1029 J E - J 1.5 x 10s Hz Formula: f= = Esh xin
