25.4 and 25.5 Frequency, wavelength, and the electromagnetic spectrum and Mathematical description of EM waves and EM wave energy

* A sinusoidal electromagnetic wave propagates in a vacuum in the positive x-direction The $\stackrel{\to }{B}$ field oscillates in the z-direction. The wavelength of the wave is 30 nm and the amplitude of the $\stackrel{\to }{B}$ field oscillations is $1.0\times {10}^{-2}$

T. (a) What is the amplitude of the $\stackrel{\to }{E}$ field oscillations? (b) Write an equation that describes the $\stackrel{\to }{B}$ field of the wave as a function of time and location. (c) Write an equation that describes the $\stackrel{\to }{E}$ field in the wave as a function of time and location (d) What type of electromagnetic radiation is this?
