The doppler. effect indicates that the universe is expanding because
a light. from. other galaxies is different colors
b light. from. other galaxies is blue. shifted
c light. from other galaxies is red. shifted
d lights from other galaxies. is the same color

Answer : The correct answer is option C.

Explanation:

Astronomers have observed that light from the distant object in the universe is shifted towards the frequency of red color which indicates that those object are receding or moving away from the planet earth.This phenomena was termed as Red shift .Same thing goes for galaxies which are very far away from the planet earth.

Where as if galaxies were moving towards the the planet earth their light would have shifted toward the frequency of blue color termed as blue shift.

Hence, the correct answer is option C.

The correct answer is option C, that is, light from other galaxies is red. Shifted.

It has been witnessed by the astronomers that the light from the distant object in the cosmo is shifted towards the red color frequency that suggests that those objects are moving away or receding from the planet Earth. This process is called Redshift. A similar thing is witnessed for galaxies that are present at very distant places from the planet Earth.  

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
