Understanding the Wave Nature of Light

Why is a green laser used in the experiment?

• Because it is the safest color to use.

• Because green light is most visible to the human eye.

• Because it is the cheapest option.

• Because it is the only color available.

What was the expected outcome when the wire was placed in the path of the laser beam?

• A completely dark screen.

• A dark line down the center of the spot.

• A rainbow pattern on the screen.

• A bright spot with no shadow.

What surprising result was observed on the screen when the wire was introduced?

• The screen remained unchanged.

• The spot turned into a rainbow.

• The spot remained bright with bands on either side.

• The spot disappeared completely.

What causes the bright regions observed on the screen?

• Destructive interference of light waves.

• Absorption of light waves by the wire.

• Constructive interference of light waves.

• Reflection of light waves.

What is the key takeaway from the demonstration regarding the nature of light?

• Light cannot be observed directly.

• Light is unaffected by obstacles.

• Light has a wave nature.

• Light behaves only as a particle.
