Question

Although an incandescent lightbulb appears to shine with constant
intensity, this is an artifact of the eye's persistence of vision. In fact, the intensity of a bulb's light rises
and falls with time due to the alternating current used in household circuits. If you could perceive these
oscillations, would you see the light attain maximum brightness 60 or 120 times per second? Explain.

3. Electromagnetic waves from a radio station pass through an open window of a house. The square window has side length 0.75 m and the waves pass through perpendicular to the window's area. The electric field is measured at the window and found to be 0.02 V/m. In air, we can use the vacuum permeability = 4 x 10-7 H/m. (i) What is the magnitude of the Poynting vector, S, for the radio waves passing through the window? (ii) How much energy do the radio waves carry through the window during a 2-minute-long broadcast of BBC Radio 4's shipping forecast? [Hint: think of the units of S [units = (J/s)/m²] and Energy [units = J].
