WebDuring the symmetric stretch, however, no dipole moment is created and so IR radiation is unable to excite this vibration. CO 2 thus absorbs at only 2 wavelengths in the IR. The difference between the number of absorptions in the IR spectrum of H 2 O and CO 2 is a consequence of the difference in their shapes (bent and linear respectively). One ... The concept of redshift and blueshift is closely related to the Doppler effect — which is an apparent shift in soundwave frequency for observers depending on whether the source is approaching or moving away from them, according to the educational website The Physics Classroom(opens in new tab). The Doppler … See more At least three types of redshift occur in the universe — from the universe's expansion, from the movement of galaxies relative to each other and from "gravitational redshift," which happens when light is shifted due to the … See more Redshift helps astronomers compare the distances of faraway objects.
