- MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A pulsar is a type of rotating neutron star that emits a beam of electromagnetic radiation. Imagine a pulsar that is moving toward Earth 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 the observed wavelength of this radiation on Earth? (Assume the Earth is stationary. Consider the speed of light c = 3.00000 × 108 m/s. Give your answer to at least six significant figures.) 4.0 133 What relationship describes the frequency of a wave for an observer that is moving relative to the source? What is the relationship between frequency and wavelength? cmcalculate the frequency of the wave whose wavelength is 10 nm a.) 2 Hz b.) 3Hz c) 1 Hz d.) 4 Hz1. Is the Doppler shift real or just a sensory illusion? Explain your answer.
