a. The components of the electric field in an electromagnetic wave traveling in vacuum are described by E_x=0, E_y=0, and E_z=6.03 sin(39.5 x - t) V/m, where x is in meters and t is in seconds. Calculate the frequency of the wave.

2. Calculate the wavelength of the wave.

3. Calculate the amplitude of the magnetic field of the wave.

4. Calculate the intensity of the wave.

5. Assuming that the source of this wave radiates isotropically, calculate the total power of that source if it is located 123 meters away.

2. Suppose a man stands in front of a mirror as shown in the figure below. His eyes are 1.65 m above the floor, and the top of his head is 0.130 m higher. Find the height above the floor of the top and bottom of the smallest mirror in which he can see both the top of his head and his feet. How is this distance related to the man's height?

3. A beam of light is shone on a corner reflector. If the angle ₁ = 50.9, what is ₂?
