How does light travel?

• In zigzag lines

• In circles

• In straight lines

• In random directions

What happens when light hits a smooth surface like a mirror?

• It gets absorbed

• It reflects off the surface

• It bends around the surface

• It disappears

What does the law of reflection state?

• Light always bends when it hits a surface

• The angle of incidence equals the angle of reflection

• Light travels faster after reflection

• Reflection only happens with curved mirrors

What is a curved mirror?

• A mirror that absorbs light

• A mirror that is flat

• A mirror that is bent inward or outward

• A mirror that changes color

What is refraction?

• The bouncing of light

• The bending of light as it passes through different materials

• The splitting of light into colors

• The disappearance of light

Which object causes light to refract?

• A wall

• A mirror

• A glass lens

• A wooden block

What do lenses do to light?

• Reflect it

• Refract it to focus or spread the rays

• Absorb it

• Block it completely

Which part of the eye controls how much light enters?

• Retina

• Lens

• Pupil

What is the function of the retina?

• To reflect light

• To block light

• To detect light and send signals to the brain

What does the lens in the eye do?

• Absorbs light

• Focuses light onto the retina

• Reflects light

• Changes light into sound
