- Draw a diagram. Determine the wavelength and frequency of the light emitted from the source.MY NOTES ASK YOUR TEACHER ANOTHER A pulsar is a type of rotating neutron star that emits a beam of electromagnetic radiation. Imagine a pulsar that is moving toware 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 x 108 m/s. Give your answer to at least six significant figures.) 4.0 cm Additional Materials O ReadingAn astronomer studying the light emitted by a star notices that the wavelength of the light is a little longer than it should be. The astronomer concludes that Select one: O a. the star is moving away from Earth O b. the star is moving toward Earth O c. the star is orbiting around Earth
