how parabolic mirror is better than concave mirror in collecting solar energy
Asked by charan3802 | 23 Oct, 2020, 10:29: AM
Expert Answer
Parabolic mirrors reduces the effect of spherical abberation which is more likely in concave mirror. 
Due to this spherical abberation, the light rays after reflection focuses at different points.
Thus, parabolic mirror is better than concave mirror in collecting solar energy.
