Question

which list provides evidence for the general theory of relativity?

constancy of the speed of light, gravitational redshift, gravitational lensing

changes in a planet’s orbital path, curvature of space time, length contraction

gravitational lensing, constancy of the speed of light, curvature of space-time

gravitational redshift, changes in a planet’s orbital path, gravitational lensing

Answer 1

Answer:

Gravitational redshift, changes in a planet’s orbital path, gravitational lensing provides the concrete evidence for the general theory of relativity.

Explanation:

• Due to the slowing of time in very 'strong gravitational field' the gravitational redshift occurs.

• The low frequency of the light occurs in the red part when we observe the electromagnetic spectrum.

• The appearance of light is seen slightly shifted to the 'red wavelength'.

• The matter in the galaxies that bends the light from a source at a distance reaching the observer is also a evidence which is termed as gravitational lensing.
