8. If red light also has a frequency of 4.3 x 10 Hz, what is the speed of red light? Show your work.

Answer all parts thanks each question is easy.

What is the story of light production here? Organize and connect the given “plot elements” and add any key elements that were omitted from the list to construct the complete story in at least five (5) complete sentences. • light radiated from the bulb   • changing magnetic field         • induced electric current motion of the bar magnet kinetic energy of the water • heat the filament What is the story of light production here?

wheel for this experiment. 2. The Apollo 11 astronauts set up a panel of efficient cor- QC ner-cube retroreflectors on the Moon's surface (Fig. 34.8a). The speed of light can be found by measuring the time interval required for a laser beam to travel from the Earth, reflect from the panel, and return to the Earth. Assume this interval is measured to be 2.51 s at a station where the Moon is at the zenith and take the center-to-center distance from the Earth to the Moon to be equal to 3.84 × 10® m. (a) What is the measured speed of light? (b) Explain whether it is nec- essary to consider the sizes of the Earth and the Moon in your calculation.
