Light

When can water reflect light?

• When it is boiling.

• When it is still.

• When it is frozen.

• When it is mixed with oil.

How does light travel through empty space?

• Light travels in a straight line without stopping.

• Light travels in a zigzag pattern.

• Light travels in circles.

• Light does not travel through empty space.

What is the role of a prism in relation to light?

• A prism can refract light and separate it into its different colors.

• A prism can absorb light and convert it into heat.

• A prism can reflect light and create shadows.

• A prism can amplify light and increase its brightness.

Can light be absorbed?

• No, light always bounces back.

• Yes, when light hits an object, it can be absorbed, meaning it does not bounce back.

• Light can only be reflected, not absorbed.

• Light can be absorbed only in a vacuum.

What is the speed of light in a vacuum?

• 150,000 kilometers per second

• 299,792 kilometers per second

• 300,000 kilometers per second

• 500,000 kilometers per second

What does translucent mean?

• Translucent materials allow light to pass through without any distortion.

• Translucent materials blur light as it passes through.

• Translucent materials completely block light.

• Translucent materials reflect all light that hits them.

What is a lens?

• A lens is a transparent object that refracts light to focus or disperse it.

• A lens is a type of camera used for capturing images.

• A lens is a device that measures the intensity of light.

• A lens is a solid object that blocks light completely.

What is a shadow?

• A shadow is formed when an opaque object blocks light from reaching a surface.

• A shadow is a reflection of an object on a surface.

• A shadow is created by the bending of light around an object.

• A shadow is the absence of light in a specific area.

What is refraction?

• Refraction is the bending of light as it passes from one medium to another.

• Refraction is the reflection of light off a surface.

• Refraction is the absorption of light by a medium.

• Refraction is the scattering of light in different directions.

What is the law of reflection?

• The angle of incidence is greater than the angle of reflection.

• The angle of incidence is equal to the angle of reflection.

• The angle of incidence is less than the angle of reflection.

• The angle of incidence and reflection are always 90 degrees.
