To understand the formula representing a traveling electromagnetic wave.

light, radiant heat (infrared radiation), x rays, and radio waves are all examples of traveling electromagnetic waves. electromagnetic waves comprise combinations of electric and magnetic fields that are mutually compatible in the sense that the changes in one generate the other.

the simplest form of a traveling electromagnetic wave is a plane wave. for a wave traveling in the x direction whose electric field is in the y direction, the electric and magnetic fields are given by

e⃗ =e0sin(kx−ωt)j^,

b⃗ =b0sin(kx−ωt)k^.

this wave is linearly polarized in the y direction.

part f

what is the wavelength λ of the wave described in the problem introduction?

express the wavelength in terms of the other given variables and constants like π.

part g

what is the period t of the wave described in the problem introduction?

express the period of this wave in terms of ω and any constants.

part h

what is the velocity v of the wave described in the problem introduction?

express the velocity in terms of quantities given in the introduction (such as ω and k) and any useful constants.

The inside surface of a cylindrical-shaped cave of inner diameter 1.0 m is continuously covered with a very thin layer of water. the cave is very long and it is open on both ends. the water on the cave surface is at a constant temperature of 15.5 °c. the cave is constantly exposed to wind such that 15.5 °c air flows through the cave at 4.5 m/s. the kinematic viscosity of the air is 14.66 x 10-6 m2/s and the molecular diffusion coefficient of water vapor in the air is 0.239 x 10-4 m2/s. because the cave diameter is so large, the flow of wind down the length of the cave, in the x direction, can be treated like it is external flow and the cave surface can be approximated as flat where appropriate. calculate the x value, in a) the transition to turbulent flow occurs at rex meters, where the air flow transitions from laminar to turbulent along the inside surface of the cave b) calculate the x value, in meters, where the bulk steady state concentration of water vapor in the air flowing in the cave is 10% of the saturation concentration. assume the air at the surface of the water layer is 100% saturated with water vapor. assume the wind entering the cave contained no moisture before it entered the cave. take into account the transition from laminar to turbulent flow when solving part b
