question 6 options:

a)

objects moving toward the earth will exhibit a blue shift

b)

objects moving toward the earth will exhibit a red shift

c)

objects moving away from earth will exhibit a blue shift

d)

objects moving away from earth will exhibit no shift

Option a)

Explanation:

According to Doppler Effect:

Red shift and Blue shift portray the movement toward longer or shorter wavelengths respectively as items in space, (for example, stars or cosmic systems) draw nearer or more remote away from us. The idea is critical to outlining the expansion of the universe.  

Visible or white light is a range of hues, which is obvious to any individual who has taken a gander at a rainbow.  

At the point when an item moves far from us, the light is moved to the red finish of the range, as its wavelengths get longer.  

On the off chance that as an object or any article draws nearer, the light moves to the blue finish of the range, as its wavelengths get shorter.

Thus the object that is moving closer to the the Earth will exhibit a shift toward the shorter wavelength, i.e., Blue shift.
