MY NOTESASK YOUR TEACHERPRACTICE ANOTHERA pulsar is a type of rotating neutron star that emits a beam of electromagnetic radiation. Imagine a pulsar that is moving towardEarth at a speed of 856.500 km/s. It emits mostly radio waves with a wavelength (at the source) of 132.500 cm. What is theobserved wavelength of this radiation on Earth? (Assume the Earth is stationary. Consider the speed of lightc = 3.00000 × 108 m/s. Give your answer to at least six significant figures.)4.0133What relationship describes the frequency of a wave for an observer that is moving relative to the source? What is the relationshipbetween frequency and wavelength? cm

Item 13 Sunspot Observations Sunspots vary in number as a function of time, exhibiting an approximately 11-year cycle. Galileo made the first European observations of sunspots in 1610, and daily observations were begun in Zurich in 1749. At the present time we are well into the 23rd observed cycle.
