Final answer:
The question pertains to the effect of redshift on the light from a star moving away from Earth. This is a concept in physics related to the Doppler effect. Without a complete formula provided in the reference information, it's not possible to confidently calculate the exact factor by which the wavelengths in the star's spectrum are changed.
Step-by-step explanation:
The question deals with the Doppler effect as applied to light coming from a traveling star or galaxy. When objects in space, such as stars or galaxies, move away from Earth, their light is redshifted. This means that the wavelengths become longer. The degree to which the wavelength is stretched depends on the relative speed between Earth and the object.
Given that the star is moving away from Earth at a speed of 41500 km/s, we can calculate the redshift to find the factor by which the wavelength is changed. Unfortunately, the provided reference information is fragmented and seems to contain either errors or incomplete data, such as a missing equation or partial values that cannot be pieced together effectively for a calculation. To calculate this precisely, the Doppler shift formula would be required, which is not provided. Therefore, I cannot confidently provide an answer to the specific question of how the wavelengths in this star's spectrum are changed.
