Find wavelength. Find Frequency. A sinusoidal electromagnetic wave in vacuum has magnetic-field amplitude 4.30 x 10-3 T and wave number 2.50 x 10Ⓡ rad/m. At a certain position and time the electric field points in the -y-direction and the magnetic field B points in the +1-direction. Find the amplitude of Ē.
Learning Goal: To understand electromagnetic radiation and be able to perform calculations involving wavelength, frequency, and energy. Several properties are used to define waves. Every wave has a wavelength, which is the distance from peak to peak or trough to trough. Wavelength, typically given the symbol A (lowercase Greek "lambda"), is usually measured in meters. Every wave also has a frequency, which is the number of wavelengths that pass a certain point during a given period of time. Frequency, given...
