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?


Which of the following are known quantities for this electromagnetic wave?
Check all that apply.
A.) frequency
B.) wavelength
C.) speed
D.) direction of propagation

Part B.) Which of the following are known quantities for this electromagnetic wave?
Check all that apply.
A.) amplitude of the electric field
B.) amplitude of the magnetic field
C.) direction of the electric field
D.) direction of the magnetic field

Explanation / Answer

For part A frequency is not known, that is what you are looking for. So it's just B,C,D
