Doppler Effect & Red Shift Exit Ticket
Use this picture to sort the following wave descriptions. Moving Towards the Person Shorter wavelength Higher frequency Higher pitch Right in Front of the Person True wavelength True frequency True pitch Moving Away from the Person Lower pitch Lower frequency Longer wavelength The spectral lines below belong to the same star. What does this tell you about the movement of the star over time? The star has moved toward us over time because it is redshifting. The star has moved away from us over time because it is redshifting. The star has moved toward us over time because it is blueshifting. The star has moved away from us over time because it is blueshifting. What tool do scientists use to measure the wavelengths given off by a star or galaxy? spectroscope telescope microscope otoscope What conclusion can be drawn by comparing the two images? The object is redshifted and moving towards earth. The object is blueshifted and is moving towards earth. The object is redshifted and moving away from earth. The object is blueshifted and moving away from earth. Most galaxies appear to us to demonstrate red shifting. This can be used as evidence for which scientific theory? parallelism expansion of the universe origin of the universe dark matter Using the data from Galaxy A and B below, which best describes their motion? Galaxy A is moving faster than B, and both are moving towards earth. Galaxy B is moving faster than A, and both are moving away from earth. Galaxy A is moving away from earth and Galaxy B is moving towards earth. Both galaxies are moving away from earth at the same speed.
