Understanding Gravity and Light

Who first predicted the existence of black holes based on the behavior of light in a gravitational field?

• Albert Einstein

• Isaac Newton

• John Mitchell

• Christian Huygens

What principle did Einstein introduce to explain the behavior of light in gravitational fields?

• Superposition Principle

• Equivalence Principle

• Uncertainty Principle

• Exclusion Principle

What phenomenon occurs when light emerges from a gravitational field?

• Gravitational blue shift

• Gravitational redshift

• Gravitational lensing

• Gravitational scattering

How does gravitational time dilation affect the path of light?

• It speeds up the light

• It bends the light

• It stops the light

• It splits the light

Which principle did Einstein use to model light's behavior in gravitational fields?

• Huygens' Principle

• Pauli Exclusion Principle

• Heisenberg Uncertainty Principle

• Archimedes' Principle

What did Einstein's calculation of light deflection by gravity reveal?

• It matched Newton's prediction

• It was twice Cavendish's prediction

• It was half of Cavendish's prediction

• It was unrelated to previous predictions

What did Sir Arthur Eddington's expedition during a solar eclipse confirm?

• Newton's theory of gravity

• Light is unaffected by gravity

• The speed of light is constant

• Einstein's deflection angle

How does the nature of light challenge our understanding of reality?

• Light is neither a wave nor a particle

• Light is both a wave and a particle

• Light is only a particle

• Light is only a wave

What is the key takeaway about the universe from the discussion on light and gravity?

• The universe is unpredictable

• The universe is self-consistent

• The universe is inconsistent

• The universe is chaotic

What does the concept of relativity suggest about our universe?

• Everything is absolute

• Nothing is observable

• Everything is relative

• Nothing is measurable
