What are cosmic gravitational waves?

Gravitational waves are ripples in the fabric of space-time that are produced when large masses accelerate. Like the detections previously reported by LIGO–Virgo, the latest ones are all attributed to pairs of dense stellar remnants spiralling into each other and merging.

What is the difference between waves and electromagnetic waves?

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space. This proved that radio waves were a form of light!

What is a difference between gravitational force and electromagnetic force?

Gravity is weaker force than Electromagnetism. Gravitational Forces are usually increased when a larger mass is accumulated, whereas Electromagnetic Forces are made when there are slight imbalances caused by small separations of charge.

What do gravitational waves do?

How are gravitational waves detected? When a gravitational wave passes by Earth, it squeezes and stretches space. A passing gravitational wave causes the length of the arms to change slightly. The observatory uses lasers, mirrors, and extremely sensitive instruments to detect these tiny changes.

How are EM waves different from other transverse waves?

Electric fields and magnetic fields (E and B) in an EM wave are perpendicular to each other and are also perpendicular to the direction of propagation of the wave. Only transverse waves can be polarized, because in a longitudinal wave, the disturbance is always parallel to the direction of wave propagation.

What are similarities between gravitational force and electromagnetic force?

Both of them have certain force which is applied of any objects. Both of them of some field area on which their force works. Both of them used to pull any objects towards them . Both of them as per the direction of the body .
