Which of the following is not an electromagnetic wave? MCQ with Answer and Explanation

Explanation:
Resolving power is a telescope's ability to distinguish closely spaced objects (like double stars) as separate. It is proportional to D / lambda, where D is the diameter (aperture) of the objective lens and lambda is the wavelength of light. Increasing the aperture D directly and strictly increases the resolving power.

Explanation:
Overcome Coulomb repulsion between nuclei, need extreme temperature and pressure.

Explanation:
r_cm = (m1 r1 + m2 r2)/(m1+m2). Closer to heavier mass.
