SP 212 Worksheet Lesson 32: Ch. 33.1-33.3, Electromagnetic Waves 1) The B-field of a light wave oscillates parallel to the y-axis and is described by By = Bm sin(kx + ωt). In what direction is the wave traveling? Write down the corresponding equation for the companion E-field of this wave. 2) What inductance must be connected to a 20.0 pF capacitor in an oscillator capable of generating electromagnetic waves of wavelength 670 nm? 3) Neodymium-glass lasers can provide 100 TW of power in 1.0 ns pulses at wavelength 0.26 µm. How much energy is contained in a single pulse? 4) Besides the sun, the closest star to our planet is the Red Dwarf Proxima Centauri, it’s about 4.24 light years away. It emits 6.54 × 1032 W of power. What is the intensity of this star’s light that we measure on Earth?
