INTERSTELLAR

What phenomenon demonstrates that light behaves as a particle?

• Reflection

• Refraction

• .Photoelectric effect

• Diffraction

Answer explanation

The photoelectric effect demonstrates that light behaves as a particle because it shows that light can eject electrons from a material when it hits it, indicating that light has particle-like properties.

In Interstellar, what is the role of light speed in the time dilation experienced by the crew?

• It accelerates the aging of the crew

• It prevents time dilation entirely

• It allows time to run slower in the spaceship

• It causes gravity to stop acting on the crew

Answer explanation

In Interstellar, the crew experiences time dilation due to their high speed relative to an outside observer. This effect allows time to run slower in the spaceship compared to Earth, making the crew age more slowly.

Which experiment shows that light also behaves like a wave?

• Double-slit experiment

• Millikan oil-drop experiment

• Rutherford gold foil experiment

• Option 4

• Stern-Gerlach experiment

Answer explanation

The double-slit experiment demonstrates that light can create an interference pattern, a hallmark of wave behavior, when passing through two slits. This experiment is pivotal in showing the wave nature of light.

In space, light can travel even though there’s no medium through which matter can pass. What does this imply about light?

• It only behaves as a wave

• It does not follow relativity

• It behaves as an electromagnetic wave

• It cannot transmit information

Answer explanation

Light can travel through the vacuum of space, indicating it behaves as an electromagnetic wave. This means it does not require a medium, unlike sound waves, which need air or another medium to propagate.

Why is the bending of light by a black hole significant in Interstellar (use general relativity)?

• It supports light’s particle nature

• It shows light is an energy field

• It confirms that light has mass

• It demonstrates gravitational lensing

Answer explanation

The bending of light by a black hole illustrates gravitational lensing, a phenomenon predicted by general relativity. It shows how massive objects can warp spacetime, affecting the path of light, which is crucial in understanding black holes.

In Interstellar, which theory of Einstein's is primarily explored through time dilation near black holes?

• Theory of Everything

• General Relativity

• Quantum Theory

• Special Relativity

Answer explanation

In Interstellar, time dilation is a key concept derived from Einstein's General Relativity, which describes how time is affected by gravity, especially near massive objects like black holes.

What causes the characters on the water planet to experience time differently from people on Earth?

• The Big Bang effect

• High gravitational field near a black hole

• Faster planetary rotation

• Presence of dark matter

Answer explanation

The characters on the water planet experience time differently due to its faster planetary rotation. This affects the passage of time relative to Earth, as time can be dilated in such conditions.

Which concept explains the expansion of the universe from a single point?

• Black Hole Theory

• Dark Matter Theory

• Big Bang Theory

• Multiverse Theory

Answer explanation

The Big Bang Theory explains the expansion of the universe from a singular point, suggesting that the universe began as a hot, dense state and has been expanding ever since.

How does Interstellar visually represent the concept of time dilation near a black hole?

• With slower speech

• By showing slower orbital rotation

• By different rates of aging

• Through warped visuals of space

Answer explanation

Interstellar visually represents time dilation by showing different rates of aging among characters. This highlights how time passes differently near a black hole, emphasizing the effects of gravity on time.

Relativity suggests that time is:

• Constant throughout the universe

• Affected by speed and gravity

• Independent of matter

• Disconnected from space

• Option 5

Answer explanation

Relativity shows that time is not constant; it is affected by speed and gravity. As an object's speed increases or it is in a strong gravitational field, time can slow down relative to an observer, making this the correct choice.
