Learning Goal: To apply Problem-Solving Strategy 23.1 Electromagnetic waves. An electromagnetic wave of wavelength 435 nm is traveling in vacuum in the -z direction. The electric field has an amplitude of 2.70 x 10-3 V/m and is parallel to the x axis. What are the frequency and the magnetic-field amplitude of this wave? Part A Which of the following are known quantities for this electromagnetic wave? Check all that apply. frequency wavelength speed direction of propagation Submit Previous Answers Correct Although the direction of propagation of the electromagnetic wave is a known quantity, it is not needed to solve this problem. > Part B Which of the following are known quantities for this electromagnetic wave? Check all that apply. U > 0 amplitude of the electric field amplitude of the magnetic field direction of the electric field direction of the magnetic field Submit Previous Answers Correct Since this problem only asks about the amplitude of the magnetic field, you will not need to use the direction of the electric field.
